admin-vsi
Function
The admin-vsi command configures the current service Virtual Switching Instance (VSI) as an mVSI.
The undo admin-vsi command configures the current mVSI as a service VSI.
By default, no mVSI is configured.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Usage Guidelines
Usage Scenario
In a virtual private LAN service (VPLS) accessing L3VPN scenario, the VRRP instance is adopted to determine whether an aggregation site gateway (ASG) is the master or backup and control the master/backup switchover. The mVSI created on the ASG is dedicated to transmitting master/backup detection packets between ASGs.
Precautions
You cannot run the shutdown command on the mVSI.
Compared with the service VSI, the mVSI becomes Up on different conditions as follows:- mVSI: requires an Up PW or an Up AC in the VSI.
- Service VSI: requires two or more Up AC interfaces, or an Up AC interface and an Up PW. When the mVSI receives a gratuitous ARP packet, it checks whether the link over which the packet is transmitted changes. If the link over which the packet is transmitted changes, the mVSI clears all the MAC addresses of service VSIs associated with the mVSI. If the link over which the packet is transmitted remains unchanged, the mVSI does not clear the MAC addresses of service VSIs associated with the mVSI.
bgp-ad
Function
The bgp-ad command creates or displays a BGP AD view.
The undo bgp-ad command deletes the created BGP AD view and all configurations in the BGP AD view.
By default, no BGP AD view is created.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
description (VSI view)
Function
The description command configures the description of a VSI.
The undo description command deletes the description of a VSI.
By default, no description is configured for a VSI.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Parameters

It is string of 1 to 128 case-sensitive characters, spaces not supported. The string cannot start at or end with a blink space. |
Usage Guidelines
Usage Scenario
To configure the description of a VSI, such as the AC interface information or other information, run the description command. The description of a VSI enables the VSI to be easily identified.
Configuration Impact
If you run this command more than once, the latest configuration overrides the previous one.

Usage Guidelines
Usage Scenario
When you run the display vsi peer-info command:
- If you specify peer-info but do not specify statistics, the command output displays the detailed PW status information about the peers of all VSIs.
- If you specify both peer-info and statistics, the command output displays the PW status statistics about the peers of all VSIs.
Precautions
If the command output does not contain PW information, the local VSI has not established any PW. In this situation, the command output shows only basic information about the local VSI.

Usage Guidelines
Usage Scenario
To check information about the AC interfaces bound to a VSI, run the display vsi services command. The command output shows the status of the VSI and AC interfaces.
Configuration Impact
If a large number of AC interfaces and VSIs exist on the device, you are advised to specify the VSI name, AC interface, and VLAN ID when using the display vsi services command. Otherwise, excess output information may cause the following problems:
- The displayed information is repeatedly refreshed and the required information cannot be obtained.
- The system does not respond because of prolonged information traversing and searching.
Example
The actual command output varies according to the device. The command output here is only an example.

encapsulation
Function
The encapsulation command configures the encapsulation type of a VSI.
The undo encapsulation command restores the default configuration.
By default, the encapsulation type of a VSI is VLAN.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Parameters
| Parameter | Description | Value |
|---|---|---|
| ethernet |
Indicates that the encapsulation type of the VSI is Ethernet. |
- |
| vlan |
Indicates that the encapsulation type of the VSI is VLAN. |
- |
Usage Guidelines
Usage Scenario
On a VPLS network, packets sent from CEs to PEs may or may not carry tags. The encapsulation type configuration affects the forwarding behavior of tagged packets.
Configuration Impact
The encapsulation type of a VSI determines whether a packet carries a tag.
Precautions
- The encapsulation types of the VSIs on both ends of a PW must be the same. For BGP VPLS, by default, Huawei devices running VRPv5 use Huawei proprietary encapsulation types, that is, encapsulation type 4 in VLAN mode and encapsulation type 5 in Ethernet mode. Huawei VRP V8 devices comply with related standards. The encapsulation type of VPLS packets is 19, regardless of whether the encapsulation type of the VSI is Ethernet or VLAN.
- The encapsulation type of the VSI is not necessarily related to the encapsulation type of the AC interface. The encapsulation types of the VSIs at both ends of a PW must be the same.
encapsulation rfc4761-compatible
Function
The encapsulation rfc4761-compatible command configures a Huawei device to use the encapsulation type defined in relevant standards for BGP VPLS packets.
The undo encapsulation rfc4761-compatible command restores the default configuration.
By default, the encapsulation types of BGP VPLS packets comply with industry standards. To be compatible with Huawei-proprietary modes (encapsulation type 4 in VLAN mode and encapsulation type 5 in Ethernet mode), run the encapsulation vpls-family-compatible command.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Usage Guidelines
Usage Scenario
By default, Huawei VRPv8 devices implement BGP VPLS based on related standards, and the encapsulation type of VPLS packets is 19. Huawei VRPv5 devices implement BGP VPLS based on Huawei-proprietary encapsulation types. In VLAN mode, the encapsulation type is 4. In Ethernet mode, the encapsulation type is 5. For Huawei VRPv5 devices, you can run the encapsulation rfc4761-compatible command to configure the devices to be compatible with the encapsulation types of related standards. For Huawei VRPv8 devices, this command is meaningless and is reserved only for upgrade compatibility.
Prerequisites
The VSI-BGP view has been displayed using the pwsignal bgp command.
Example
<HUAWEI> system-view [HUAWEI] mpls [HUAWEI-mpls] quit [HUAWEI] mpls l2vpn [HUAWEI-l2vpn] quit [HUAWEI] vsi bgp1 auto [HUAWEI-vsi-bgp1] pwsignal bgp [HUAWEI-vsi-bgp1-bgp] encapsulation rfc4761-compatible
encapsulation vpls-family-compatible
Function
The encapsulation vpls-family-compatible command configures a Huawei device to use encapsulation type 4 or 5 for BGP VPLS packets, depending on whether the user access mode is VLAN or Ethernet.
The undo encapsulation vpls-family-compatible command restores the default configuration.
By default, a Huawei device uses the encapsulation type defined in relevant standards for BGP VPLS packets.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Usage Guidelines
Usage Scenario
By default, VRPv8-based new Huawei devices implement BGP VPLS in compliance with industry standards. That is, the encapsulation type of VPLS packets is 19. VRPv5-based existing Huawei devices implement BGP VPLS based on the Huawei-proprietary encapsulation types, that is, the VLAN encapsulation type is 4, and the Ethernet encapsulation type is 5. To enable VRPv8-based new devices and VRPv5-based existing devices to communicate with each other, you need to run the encapsulation vpls-family-compatible command to change the encapsulation type.
When a device is sending packets, you need to run the encapsulation vpls-family-compatible command to configure the device to covert the encapsulation type from 19 to the Huawei-proprietary one (4 or 5). When the device is receiving packets, the encapsulation type can be changed automatically without any manual configuration. The packet encapsulation mode on an AC-side interface is determined by the user access mode. User access modes are classified into VLAN access and Ethernet access.- VLAN access: Ethernet frames transmitted between a CE and a PE have a VLAN tag. The tag is a service delimiter required by an ISP to differentiate users. It is also called the provider tag (P-tag).
- Ethernet access: An Ethernet frame header transmitted between a CE and a PE does not have any service delimiter. If the header has a VLAN tag, the tag is the inner VLAN tag of user packets and is meaningless to the PE. The internal user VLAN tag is called the user-tag (U-tag).
Prerequisites
The VSI-BGP view has been displayed using the pwsignal bgp command.
Example
<HUAWEI> system-view [HUAWEI] mpls [HUAWEI-mpls] quit [HUAWEI] mpls l2vpn [HUAWEI-l2vpn] quit [HUAWEI] vsi bgp1 auto [HUAWEI-vsi-bgp1] pwsignal bgp [HUAWEI-vsi-bgp1-bgp] encapsulation vpls-family-compatible
flow-label (VSI-LDP view)
Function
The flow-label command enables flow-label-based load balancing for an L2VPN VSI.
The undo flow-label command disables flow-label-based load balancing of an L2VPN VSI.
By default, flow-label-based load balancing of L2VPN VSIs is disabled.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Format
flow-label { both | send | receive } [ static ]
undo flow-label { both | send | receive } [ static ]
undo flow-label
Parameters
| Parameter | Description | Value |
|---|---|---|
| both |
Configures the local end to send and receive packets based on flow labels. |
- |
| send |
Configures the local end to send packets based on flow labels. |
- |
| receive |
Indicates the capability to receive packets based on flow labels on the local device. |
- |
| static |
Statically configures flow-label-based load balancing. |
- |
Usage Guidelines
Usage Scenario
When multiple links exist between P devices, configure flow-label-based load balancing to improve L2VPN traffic forwarding efficiency. After flow-label-based load balancing is enabled on a PE, the PE adds different labels for different L2VPN data flows to distinguish them one from the other. After a P device receives a data packet carrying a flow label, it selects a forwarding path based on the flow label in the data packet. This processing implements load balancing.
To enable flow-label-based load balancing for all PWs in a VSI, run the flow-label command in the VSI-LDP view.Prerequisites
MPLS L2VPN has been enabled.
MPLS L2VPN has been enabled.
The mpls (load balancing profile view) command has been run to configure a load balancing mode for MPLS packets in a load balancing profile. This prerequisite applies only to S6780-Hs, S6750-Hs, and S6750-Ss.Precautions
When configuring flow label-based load balancing for an L2VPN, note the following:
- Flow label-based load balancing can be successfully configured only when the send and receive parameters configured on both ends of the PW match.
- The receive parameter is configured on the local PE, and the send parameter is configured on the remote PE.
- The send parameter is configured on the local PE, and the receive parameter is configured on the remote PE.
- Flow label-based load balancing is enabled in the receive and transmit directions on both the local and remote ends.
- If the static flow label-based load balancing configuration does not match on both ends, the device discards packets carrying flow labels, causing packet loss.
- During the configuration of flow label-based load balancing, PWs are renegotiated. As a result, services temporarily go down and then up again, and this may cause traffic loss.
flow-label (VSI-LDP-PW view)
Function
The flow-label command enables flow-label-based load balancing for an L2VPN PW.
The undo flow-label command disables flow-label-based load balancing of an L2VPN PW.
The flow-label disable command disables flow-label-based load balancing of an L2VPN PW.
The undo flow-label disable command restores flow-label-based load balancing of an L2VPN PW.
By default, a PW has the same L2VPN flow label-based load balancing capability as the VSI to which it belongs.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Format
flow-label { { both | send | receive } [ static ] | disable }
undo flow-label { { both | send | receive } [ static ] | disable }
undo flow-label
Parameters
| Parameter | Description | Value |
|---|---|---|
| both |
Indicates both the send and receive capabilities of flow-label-based load balancing for the local device. |
- |
| send |
Configures the local end to send packets based on flow labels. |
- |
| receive |
Indicates the capability to receive packets based on flow labels on the local device. |
- |
| static |
Statically configures flow-label-based load balancing. |

Usage Guidelines
Usage Scenario
When multiple links exist between P devices, configure flow-label-based load balancing to improve L2VPN traffic forwarding efficiency. After flow-label-based load balancing is enabled on a PE, the PE adds different labels for different L2VPN data flows to distinguish them. After a P device receives a data packet carrying a flow label, it selects a forwarding path based on the flow label in the data packet.
To enable flow-label-based load balancing for a specific L2VPN PW, run the flow-label command. Note that:- If flow-label-based load balancing is configured for both a VSI and a PW in this VSI, the configuration of the PW takes precedence.
- If the undo flow-label command is run in the VSI-LDP-PW view, only the flow-label-based load balancing capability that has been configured using the flow-label command in the VSI-LDP-PW view is disabled.
- If the flow-label command has been run for a VSI but not for a PW, you can run the flow-label disable command in the VSI-LDP-PW view to disable flow-label-based load balancing of the PW. If the PW needs the flow-label-based load balancing capability again, you can run the undo flow-label disable command to restore flow-label-based load balancing.
Prerequisites
MPLS L2VPN has been enabled.
MPLS L2VPN has been enabled.
The mpls (load balancing profile view) command has been run to configure a load balancing mode for MPLS packets in a load balancing profile. This prerequisite applies only to S6780-Hs, S6750-Hs, and S6750-Ss.Precautions
When configuring flow label-based load balancing for an L2VPN, pay attention to the following points:
- Flow label-based load balancing can be successfully configured only when the send and receive parameters configured on both ends of the PW match.
- The receive parameter is configured on the local PE, and the send parameter is configured on the remote PE.
- The send parameter is configured on the local PE, and the receive parameter is configured on the remote PE.
- Flow label-based load balancing is enabled in both the transmit and receive directions on the local and remote ends.
- If the static flow label-based load balancing configuration does not match on both ends, the device discards packets carrying flow labels, causing packet loss.
- After the flow label is configured, the PW is renegotiated. As a result, the service goes Down and then Up.

holdoff (Protection group view)
Function
The holdoff command configures a switching delay for a PW protection group with the master/slave PW redundancy mode.
The undo holdoff command deletes the switching delay for a PW protection group with the master/slave PW redundancy mode.
By default, no switching delay is configured for a PW protection group with the master/slave PW redundancy mode. In this situation, if a fault occurs on the primary PW, traffic immediately switches from the primary PW to the secondary PW.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.

The value is an integer ranging from 1 to 180, in seconds. |
Usage Guidelines
Usage Scenario
By default, no switching delay is configured for a PW protection group with the master/slave PW redundancy mode. In this case, if a fault occurs on the primary PW, traffic is immediately switched from the primary PW to the secondary PW.
Prerequisites
The PW redundancy mode of the PW protection group has been configured as master/slave.
Configuration Impact
If the holdoff command is run more than once, the latest configuration overrides the previous one.
After you configure a switching delay, traffic forwarded during the delay period will be interrupted if the primary PW fails to recover before the delay period expires.Precautions
The independent PW redundancy mode does not support delayed switching.
On a VPLS network configured with BFD, if a fault is detected on the working link, a physical link switchover is performed immediately. Therefore, you are advised to configure BFD or delayed switching as required. After the hold-off time is configured, if the primary link fails, traffic forwarding is interrupted during this period.Example

hub-mode enable
Function
The hub-mode enable command changes the VSI attribute on an interface from spoke to hub.
The undo hub-mode enable command changes the VSI attribute on an interface from hub to spoke.
By default, the VSI attributes on the AC and PW sides are spoke and hub, respectively.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.

Usage Guidelines
Usage Scenario
You can run the hub-mode enable command on a PE to change the AC attribute of a VSI from spoke to hub. In this manner, traffic cannot be forwarded between AC interfaces in hub mode, achieving forwarding isolation.
After you run the isolate spoken command, traffic forwarding is prohibited between AC interfaces in a VSI. If traffic forwarding is required between some AC interfaces in the VSI, run the hub-mode enable command to implement on-demand traffic isolation.Prerequisites
A VSI has been created and bound to an interface.
Precautions
If the hub-mode enable command is run on two local AC interfaces, the two AC interfaces cannot communicate with each other and can only communicate with other AC interfaces that are not configured with the hub-mode enable command.

ignore-ac-state
Function
The ignore-ac-state command configures the VSI status not to be affected by AC status changes.
The undo ignore-ac-state command restores the default configuration.
By default, AC status changes affect the VSI status.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Usage Guidelines
Usage Scenario
If the services running on a legacy network need to switch to a new network, you can configure VSIs to ignore the AC status and check whether the VSIs on the new network can work properly. A VSI can be up only if an AC interface or UPE PW is up and the PW status is up. After you configure a VSI to ignore AC interface status changes, the VSI remains up as long as one PW is up, regardless of whether the AC interface status is up or down.
The AC status has two meanings:- Status of the physical or logical interface bound to the VSI
- UPE PW status in a VLL accessing VPLS scenario
To configure all VSIs on a device to ignore the AC interface status, run the vpls ignore-ac-state command.
To configure a VSI on a device to ignore the AC interface status, run the ignore-ac-state command.Configuration Impact
After the ignore-ac-state command is configured, the VSI status will not be affected by AC status changes. A VSI can go Up even if no AC is connected to the VSI.
Follow-up Procedure
After service switching, run the undo ignore-ac-state command to restore the default configuration.
interface-parameter-type vccv
Function
The interface-parameter-type vccv command restores the VCCV byte (an interface parameter) in the Mapping packet.
The undo interface-parameter-type vccv command deletes the VCCV byte in the Mapping packet.
By default, a Mapping packet carries the VCCV byte.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Usage Guidelines
Usage Scenario
If LDP VPLS is configured for a device running V800R005 or later to communicate with the devices running VRP V300R001 or branch versions, configure the undo interface-parameter-type vccv command.
Precautions
Note that the command can be configured only for the corresponding local VPLS.

interface-status-change mac-withdraw enable
Function
The interface-status-change mac-withdraw enable command configures a PE to send LDP MAC Withdraw messages to all peers when the status of the AC interface bound to the VSI changes.
The undo interface-status-change mac-withdraw enable command disables a PE from sending LDP MAC Withdraw messages to all peers when the status of the AC interface bound to the VSI changes.
By default, a VSI does not send LDP MAC Withdraw messages.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Format
interface-status-change [ up | down ] mac-withdraw enable
undo interface-status-change [ up | down ] mac-withdraw enable
Parameters
| Parameter | Description | Value |
|---|---|---|
| up |
Configures a PE to send MAC Withdraw messages with the 0x404 TLV type to all peers when the bound AC interface goes Up. After a peer receives a MAC Withdraw message with the 0x404 TLV type, it clears MAC addresses in the VSI. |
- |
| down |
Configures a PE to send MAC Withdraw messages with the 0x406 TLV type to all peers when the bound AC interface goes Down. After a peer receives a MAC Withdraw message with the 0x406 TLV type, it clears MAC addresses learned by the VSI over a specific PW. |
- |
Usage Guidelines
By default, when the status of an AC interface changes, the PE does not send an LDP MAC Withdraw message to the peer. As a result, the peer cannot detect that the CE corresponding to the AC interface is unreachable, and traffic destined for the CE is lost before the MAC address in the VSI is aged out. To solve this problem, run the interface-status-change mac-withdraw enable command. Then, when the AC interface status changes, the PE sends LDP MAC Withdraw messages to all peers. After receiving the LDP MAC Withdraw messages, the peers clear MAC address information of a VSI based on the types of LDP MAC Withdraw messages:
- If an AC interface goes down or the binding between an AC interface in the up state and a VSI is canceled, the PE sends an LDP MAC Withdraw message with the type of 406 to the peer. After the peer receives this LDP MAC Withdraw message, it clears the MAC addresses learned from the specified PW in the VSI.
- If an AC interface goes up or an AC interface in the up state is bound to a VSI, the PE sends an LDP MAC Withdraw message with the type of 404 to the peer. After the peer receives this LDP MAC Withdraw message, it clears MAC addresses in the VSI.
Example
<HUAWEI> system-view [HUAWEI] mpls [HUAWEI-mpls] quit [HUAWEI] mpls l2vpn [HUAWEI-l2vpn] quit [HUAWEI] vsi v1 static [HUAWEI-vsi-v1] interface-status-change mac-withdraw enable
interface-status-change mac-withdraw enable (VSI-LDP view)
Function
The interface-status-change mac-withdraw enable command configures a PE to send LDP MAC Withdraw messages to all peers when the status of the AC interface bound to the VSI changes.
The undo interface-status-change mac-withdraw enable command disables a PE from sending LDP MAC Withdraw messages to all peers when the status of the AC interface bound to the VSI changes.
By default, a VSI does not send LDP MAC Withdraw messages.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Format
interface-status-change [ up | down ] mac-withdraw enable
undo interface-status-change [ up | down ] mac-withdraw enable
Parameters
| Parameter | Description | Value |
|---|---|---|
| up |
Configures a PE to send MAC Withdraw messages with the 0x404 TLV type to all peers when the bound AC interface goes Up. After a peer receives a MAC Withdraw message with the 0x404 TLV type, it clears MAC addresses in the VSI. |
- |
| down |
Configures a PE to send MAC Withdraw messages with the 0x406 TLV type to all peers when the bound AC interface goes Down. After a peer receives a MAC Withdraw message with the 0x406 TLV type, it clears MAC addresses learned by the VSI over a specific PW. |
- |
Usage Guidelines
Usage Scenario
By default, when the status of an AC interface on a PE changes, the PE does not send MAC Withdraw messages to its peers. As a result, its peers are unaware of the fact that the CE connecting to that AC interface is unreachable. Subsequently, traffic bound to the CE gets lost before MAC addresses in the VSI age out. To solve this problem, run the interface-status-change mac-withdraw enable command. Then, when the AC interface status changes, the PE sends a MAC Withdraw message to all its peers. After a peer receives the MAC Withdraw message, it clears MAC addresses in the VSI based on the MAC Withdraw message type.
- When the status of an AC interface changes from Up to Down or an AC interface in the Up state leaves a VSI, the PE sends MAC Withdraw messages with the 0x406 TLV type to its peers. Upon receipt, a peer clears the MAC addresses learned over the specified PW from the VSI.
- When the status of an AC interface changes from Down to Up or an AC interface in the Up state joins a VSI, the PE sends MAC Withdraw messages with the 0x404 TLV type to its peers. Upon receipt, a peer clears MAC addresses in the VSI.
Precautions
This command takes effect only after the mac-withdraw enable command is also used.

isolate spoken
Function
The isolate spoken command enables forwarding isolation between AC interfaces, between UPE PWs, and between AC interfaces and UPE PWs in a VSI.
The undo isolate spoken command disables forwarding isolation between AC interfaces, between UPE PWs, and between AC interfaces and UPE PWs in a VSI.
By default, forwarding isolation between AC interfaces, between UPE PWs, and between AC interfaces and UPE PWs in a VSI is disabled.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Usage Guidelines
Usage Scenario
If users using the same services are bound to the same VSI, you can use the isolate spoken command to prevent the users from communicating with each other. When using the
isolate spoken command, note the following:- For ordinary VPLS, communications between AC interfaces are prohibited.
- For HVPLS, communications between AC interfaces, between AC interfaces and UPE PWs, and between UPE PWs are prohibited.
Prerequisites
A signaling protocol has been configured for the VSI instance.
Precautions
- If IGMP snooping is disabled in a VSI, running the isolate spoken command isolates all packets, including unicast, broadcast, and multicast packets (IGMP multicast packets are no exception).
- If IGMP snooping is enabled in a VSI:
- Running the isolate spoken command isolates all packets except IGMP multicast packets, including unicast and broadcast packets.

l2 binding vsi
Function
The l2 binding vsi command binds a VSI to an interface.
The undo l2 binding vsi command restores the default configuration.
By default, a VSI instance is not bound to an interface.
By default, a multi-homing site is not bound to any AC interface.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Parameters
| Parameter | Description | Value |
|---|---|---|
| vsi vsi-name |
Specifies the name of the VSI to be bound to an interface. The VSI name specified here must be consistent with that specified in the vsi vsi-name command. |
The value is a string of 1 to 31 case-sensitive characters without spaces. The character string can contain spaces if it is enclosed with double quotation marks ("). |

Usage Guidelines
Usage Scenario
After creating and configuring a VSI, you must run the l2 binding vsi command on an AC interface to bind the AC interface to the VSI.
Prerequisites
A VSI has been created and configured. For example, the VSI ID and peer IP address have been configured.
Configuration Impact
After an interface is bound to a VSI, the interface can no longer be configured with Layer 3 services, such as the IP address. VPWS or L3VPN cannot be configured either.
Follow-up Procedure
After an interface is bound to a VSI, you can run the display vsi command to view whether the VSI status is Up, according to which you can find whether the PW is set up successfully for the VSI.
Precautions
The CE interfaces connected to the AC interfaces on the two ends cannot be allocated the same IP address.
VXLAN and VPLS are mutually exclusive. If VXLAN is configured on an AC interface, you cannot run the l2 binding vsi command to bind the AC interface to a VSI. If the user-queue, qos-profile, car, or qos hard-pipe bandwidth command is run on an interface, the l2 binding vsi command cannot be used to bind the interface to a VSI with hard pipe enabled. Otherwise, an error message is displayed. A local VSI in P2P mode does not support the use of QinQ/dot1q VLAN tag termination sub-interfaces, QinQ stacking sub-interfaces, QinQ mapping sub-interfaces, flexible sub-interfaces, or VE interfaces as AC interfaces. VPLS multi-homing blocks data packets on the backup PE's AC interface to prevent loops. There is no need to deploy additional loop protection protocols such as STP or MAC Flapping. If STP/MAC flapping-based loop detection is deployed, the standby PE does not block Layer 2 protocol packets on its AC interface. The AC interfaces of the active and standby PEs may both be blocked, interrupting traffic.If an Ethernet interface has sub-interfaces, the interface cannot be bound to an L2VPN service.

local-mac remove all-but-mine
Function
The local-mac remove all-but-mine command configures a VSI to delete all the MAC address entries learned from PWs and AC interfaces, except the entries learned from the PW that sends the MAC Withdraw message with the TLV type of 0x404.
The undo local-mac remove all-but-mine command restores the default configuration.
By default, a VSI deletes all the MAC address entries learned from PWs and AC interfaces after receiving a MAC Withdraw message with the TLV type of 0x404.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Usage Guidelines
Usage Scenario
A CE is dual-homed to two PEs on a VPLS network. If a PE finds that an AC fault is removed, the PE sends MAC Withdraw messages with the TLV type of 0x404 to instruct the remote PE to update MAC address entries and perform a traffic switchback. In a scenario where a CE is dual-homed to a VPLS network, the primary link is CE1 --> PE2 --> PE1 --> CE2 and the backup link is CE1 --> PE3--> PE1 --> CE2. CE1 connects to CE2 over the primary and backup links. Path PE2 --> PE1 is the primary one, and path PE3 --> PE1 is the backup one. After path CE1 --> PE2 recovers, PE2 sends a MAC Withdraw message with the TLV type of 0x404 to PE1. After receiving the message, PE1 retains only the MAC address corresponding to path PE2 --> PE1 according to related standards, and deletes other MAC addresses. In this manner, downstream traffic is switched back to path PE2 --> PE1.
To provide standard processing for MAC Withdraw messages with the TLV type of 0x404, run the local-mac remove all-but-mine command. You only need to run this command on PE1.Precautions
This command takes effect on a PE that receives MAC Withdraw messages with the TLV type of 0x404.
Example
<HUAWEI> system-view [HUAWEI] mpls [HUAWEI-mpls] quit [HUAWEI] mpls l2vpn [HUAWEI-l2vpn] quit [HUAWEI] vsi vsi1 [HUAWEI-vsi-vsi1] local-mac remove all-but-mine
mac-learning
Function
The mac-learning enable command enables MAC address learning.
The mac-learning disable command disables MAC address learning.
The undo mac-learning disable command enables MAC address learning.
By default, MAC address learning is enabled.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Usage Guidelines
Usage Scenario
After MAC address learning is disabled, VPLS can be simulated as VPWS. For example, if there are only two PEs and each PE is connected to only one CE, disabling MAC address learning on the PEs mitigates the MAC address learning pressure on them.
Configuration Impact
After the mac-learning disable command is run, the device can no longer automatically learn MAC addresses, causing packets to be broadcast on the network. Exercise caution when using this command.
mac-withdraw enable
Function
The mac-withdraw enable command configures a VSI to instruct all the remote peers to delete all the MAC addresses learned from this VSI when an AC or PW fault occurs and the VSI remains up.
The undo mac-withdraw enable command disables a VSI from instructing all the remote peers to delete all the MAC addresses learned from this VSI when an AC or PW fault occurs and the VSI remains up.
By default, MAC Withdraw is disabled.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Usage Guidelines
Usage Scenario
On an LDP VPLS network, VSIs depend on MAC address entries to transmit traffic. If the AC or PW status changes, VSIs need to update the MAC entries immediately to reduce the traffic loss. The mac-withdraw enable command enables a PE to send a MAC Withdraw message to all its remote peers to inform them of the AC or PW status change (if any). After the peers receive the message, they remove the MAC address entries in their VSIs based on the message.
Configuration Impact
After MAC Withdraw is enabled, the MAC addresses learned from the remote end may be deleted from the local end when the AC or PW goes up or down and packet broadcasting may occur.
Example
<HUAWEI> system-view [HUAWEI] mpls [HUAWEI-mpls] quit [HUAWEI] mpls l2vpn [HUAWEI-l2vpn] quit [HUAWEI] vsi v100 [HUAWEI-vsi-v100] mac-withdraw enable
mac-withdraw enable (VSI-LDP view)
Function
The mac-withdraw enable command configures a VSI to instruct all the remote peers to delete all the MAC addresses learned from this VSI when an AC or PW fault occurs and the VSI remains up.
The undo mac-withdraw enable command disables a VSI from instructing all the remote peers to delete all the MAC addresses learned from this VSI when an AC or PW fault occurs and the VSI remains up.
By default, MAC Withdraw is disabled.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Usage Guidelines
Usage Scenario
On an LDP VPLS network, VSIs depend on MAC address entries to transmit traffic. If the AC or PW status changes, VSIs need to update the MAC entries immediately to reduce the traffic loss. The mac-withdraw enable command enables a PE to send a MAC Withdraw message to all its remote peers to inform them of the AC or PW status change (if any). After the peers receive the message, they remove the MAC address entries in their VSIs based on the message.
Configuration Impact
After MAC Withdraw is enabled, the MAC addresses learned from the remote end may be deleted from the local end when the AC or PW goes up or down and packet broadcasting may occur.

mac-withdraw propagate enable
Function
The mac-withdraw propagate enable command enables a PE to forward a received MAC Withdraw message to its peers.
The undo mac-withdraw propagate enable command disables a PE from forwarding a received MAC Withdraw message to its peers.
By default, a PE does not forward a received MAC Withdraw message.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Usage Guidelines
Usage Scenario
On an LDP or BGP AD VPLS network, after a local PE receives a MAC Withdraw message, the local PE needs to forward the MAC Withdraw message to its peers. Otherwise, its peers cannot detect network topology changes or learn new MAC addresses in a timely manner. As a result, traffic loss caused by invalid MAC addresses will occur. To enable a PE to forward a received MAC Withdraw message to its peers, run the mac-withdraw propagate enable command.
Precautions
- After you run the mac-withdraw propagate enable command on a PE, the PE forwards a received MAC Withdraw message to its peers according to the split horizon rule:
- The MAC Withdraw message received from a UPE will be forwarded to NPEs and other UPEs.
- The MAC Withdraw message received from an NPE will be forwarded to UPEs, but will not be forwarded to other NPEs.
- The mac-withdraw propagate enable command applies to MAC Withdraw messages carrying either the FEC 128 TLV or the FEC 129 TLV. The upe-upe mac-withdraw enable, upe-npe mac-withdraw enable, and npe-upe mac-withdraw enable commands apply only to MAC Withdraw messages carrying the FEC 128 TLV. The mac-withdraw propagate enable command cannot be used with the upe-upe mac-withdraw enable, upe-npe mac-withdraw enable, or npe-upe mac-withdraw enable command in the same VSI.
mpls l2vpn default vlan
Function
The mpls l2vpn default vlan command configures a default VLAN for a main interface.
The undo mpls l2vpn default vlan command deletes the default VLAN of a main interface.
By default, no default VLAN is configured for a main interface.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Parameters
| Parameter | Description | Value |
|---|---|---|
| vlanId |
Specifies the default VLAN ID for a main interface. |
The value is an integer ranging from 1 to 4094. |
Views
100GE interface view, 10GE interface view, 25GE interface view, 400GE interface view, 40GE interface view, Eth-Trunk interface view, GE optical interface view, GE interface view, GE electrical interface view, Multi-GE interface view
Usage Guidelines
Usage Scenario
When the following conditions are met, you can run the mpls l2vpn default vlan command to specify the default VLAN for a main interface:
- The VPWS or VSI using VLAN encapsulation is configured on the endpoint PEs.
- The remote PE accepts only tagged packets.
- The local PE uses the main interface as the AC interface to connect to the PC. In this scenario, the PC sends and receives only untagged packets. After the default VLAN is specified for the main interface, the local PE performs the following operations:
- The local PE adds VLAN tags to the packets sent by the PC. A VLAN tag is encapsulated into each user packet and transparently transmitted to the remote PE.
- The local PE removes VLAN tags from packets sent by the remote PE and forwards these packets to the PC through an AC interface.
Precautions
Before binding a main interface to the VPWS or VSI, you need to run the mpls l2vpn default vlan command to specify the default VLAN for the main interface.
After a main interface is bound to a VSI, the mpls l2vpn default vlan command configuration cannot be modified. To modify the configuration, you must unbind the main interface from the VSI first. This operation will interrupt VPLS services on the main interface. Exercise caution when performing this operation. If the remote PE can replace the VLAN tag in received packets with the VLAN tag of its AC-side outbound interface when terminating the PW, the default VLAN for the main interface of the local PE can be set to any VLAN. Otherwise, the default VLAN for the main interface must be the same as the VLAN of the AC-side outbound interface on the remote PE. If the main interface of a switch is used as the AC-side interface of a PE, you need to run the undo portswitch command to switch the Layer 2 interface to a Layer 3 interface before running the mpls l2vpn default vlan command. This command and the mpls l2vpn vlan-stacking stack-vlan command are mutually exclusive.mpls l2vpn vlan-stacking
Function
The mpls l2vpn vlan-stacking command configures a main interface to add a stack VLAN tag to packets passing through the interface.
The undo mpls l2vpn vlan-stacking command disables a main interface from adding a stack VLAN tag to packets.
By default, the system does not add a VLAN tag to a packet passing through the main interface.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Format

Usage Guidelines
Usage Scenario
When the following conditions are met, run the mpls l2vpn vlan-stacking stack-vlan command to specify a stack VLAN for a main interface:
- The VPWS or VSI using VLAN encapsulation is configured on the endpoint PEs.
- The remote PE accepts packets with the stack VLAN tag.
- The local PE uses the main interface as the AC interface to connect to the PC.
In this scenario, the PC sends and receives all packets. After a stack VLAN is specified for the main interface, the local PE performs the following operations:
- The local PE adds VLAN tags to the packets sent by the PC. A VLAN tag is encapsulated into each user packet and transparently transmitted to the remote PE.
- The local PE removes outermost VLAN tags from packets sent by the remote PE and forwards these packets to the PC through an AC interface.
Precautions
Before binding the main interface to the VPWS or VSI, run the mpls l2vpn vlan-stacking stack-vlan command to specify a stack VLAN for the main interface.
After a main interface is bound to a VSI, the mpls l2vpn vlan-stacking stack-vlan command configuration cannot be modified. To modify the configuration, you must unbind the main interface from the VSI first. This operation will interrupt VPLS services on the main interface. Exercise caution when performing this operation. When a main interface is used as an AC interface, run the undo portswitch command to switch the Layer 2 interface to a Layer 3 interface. This command and the mpls l2vpn default vlan command are mutually exclusive.mtu-negotiate disable
Function
The mtu-negotiate disable command disables the MTU check for a VSI.
The undo mtu-negotiate disable command restores the default configuration.
By default, the MTU check is enabled for a VSI.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Usage Guidelines
Usage Scenario
The default MTU is 1500 bytes for a VSI. On a BGP VPLS network, two PEs cannot establish a PW if their VSI MTUs are different. To prevent this problem, use either of the following methods: - Run the mtu command to set the MTU of the VSI. Ensure that the MTUs at both ends of the VC are the same. - Run the mtu-negotiate disable command to disable the VSI MTU check.
Prerequisites
The VSI-BGP view has been displayed using the pwsignal bgp command.
Configuration Impact
After the mtu-negotiate disable command is run on a PE, the PE does not perform any MTU check on VPLS packets received from the same VSI. If other conditions for establishing a PW are met, the PW goes up.
npe-upe mac-withdraw enable
Function
The npe-upe mac-withdraw enable command enables a superstratum provider edge (SPE) to forward the LDP MAC Withdraw messages received from network provider edges (NPEs) to underlayer provider edges (UPEs).
The undo npe-upe mac-withdraw enable command disables an SPE from forwarding the LDP MAC Withdraw messages received from NPEs to UPEs.
By default, an SPE does not forward the LDP MAC Withdraw messages received from other NPEs to UPEs.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Usage Guidelines
This command is mainly used on the gateway on the Metro Ethernet where:
- NPE refers to the network end peer of the local VSI in HVPLS. You can run the peer peer-address [ negotiation-vc-id vc-id ] [ tnl-policy policy-name ] command to specify an NPE.
- UPE refers to the user end peer of the local VSI in HVPLS. You can run the peer peer-address [ negotiation-vc-id vc-id ] [ tnl-policy policy-name ] upe command to specify a UPE.
- If the local device is not configured with HVPLS, the npe-upe mac-withdraw enable command is not required.
peer
Function
The peer command configures a static UPE peer in an H-VPLS VSI.
The undo peer command deletes a static UPE peer from an H-VPLS VSI.
By default, no static UPE peer is configured in an H-VPLS VSI.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Format
peer peer-address [ negotiation-vc-id pwIdValue ] [ tnl-policy policy-name ] { static-npe | static-upe } trans transmit-label recv receive-label
undo peer peer-address [ negotiation-vc-id pwIdValue ] [ tnl-policy policy-name ] { static-npe | static-upe } trans transmit-label recv receive-label
Parameters
| Parameter | Description | Value |
|---|---|---|
| peer-address |
Specifies the IPv4 address of a static peer. The loopback address of the peer is usually used as its IPv4 address. |
The value is in dotted decimal notation. |
| negotiation-vc-id pwIdValue |
Specifies the unique VC ID. This parameter is used when two ends with different VSI IDs need to communicate with each other. The vc-id value must be different from the IDs of other local VSIs. The VC IDs specified using negotiate-vc-id must be different on a peer. |
The value is an integer ranging from 1 to 4294967295. |
| tnl-policy policy-name |
Specifies the name of the tunnel policy used by the static remote peer. |
The value is a string of 1 to 39 case-sensitive characters, spaces not supported. If the string is enclosed in quotation marks, the string can contain spaces. |
| static-npe |
Indicates a static NPE peer. |
- |
| static-upe |
Indicates a static UPE peer. |
- |
| trans transmit-label |
Specifies the value of the inner label sent from the local device to the peer, that is, the outgoing label of the static Layer 2 VC. |
The value is an integer ranging from 0 to 1048575. |
| recv receive-label |
Specifies the value of the inner label sent from the peer to the local device, that is, the incoming label of the static Layer 2 VC. |
The value is an integer ranging from 16 to 65551. |
Usage Guidelines
Usage Scenario
If devices are unable to support large numbers of LDP sessions or you want to manually manage and allocate VC labels, run the peer static-upe command to configure static VPLS PWs. When VPLS PWs are created using manually configured VC labels, Layer 2 VC or link information does not need to be transmitted using LDP.
Prerequisites
The VSI ID has been configured using the vsi-id vsi-id command.
Precautions
If you specify negotiation-vc-id vc-id during the configuration of a static VPLS PW and the specified vc-id value is different from the vsi-id value configured using the vsi-id command, you must specify negotiation-vc-id vc-id when using the undo peer command to delete a VPLS PW from the VSI.

peer (VSI-LDP view)
Function
The peer command specifies a peer for a VSI.
The undo peer command deletes the peer specified for a VSI.
By default, no peer is specified for a VSI.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Format
peer peer-address [ negotiation-vc-id vc-id ] [ tnl-policy policy-name ] [ upe ] [ ignore-standby-state ]
undo peer peer-address [ negotiation-vc-id vc-id ] [ tnl-policy policy-name ] [ upe ] [ ignore-standby-state ]
Parameters
| Parameter | Description | Value |
|---|---|---|
| peer-address |
Specifies the IPv4 address of a peer, which is usually the loopback address of the peer. The value must be the same as the destination IP address of the tunnel. |
The value is in dotted decimal notation. |
| negotiation-vc-id vc-id |
Specifies the circuit number of a VC. The circuit number uniquely identifies a VC. It is used when two ends with different VSI IDs need to communicate with each other. |
The value is an integer that ranges from 1 to 4294967295. vc-id cannot be the same as any other local VSI IDs or any other VSI IDs specified by negotiate-vc-id on the local end. That is, vc-id must be an unused one. If negotiate-vc-id is configured on the local end, negotiate-vc-id or vsi-id configured on the peer end must be the same as negotiate-vc-id configured on the local end. |
| tnl-policy policy-name |
Specifies the tunnel policy name of the peer. The tunnel policy name must be the same as that specified in the tunnel-policy command run in the system view. |
The value is a string of 1 to 39 case-sensitive characters, spaces not supported. By default, LDP LSPs are used. |
| upe |
Specifies whether the peer is a client PE. This parameter applies to Hierarchical Virtual Private LAN Service (HVPLS). This parameter is used to specify a UPE peer on an SPE. |
- |
| ignore-standby-state |
Configures the created PW to ignore the standby state notified by the remote end. |
- |
Usage Guidelines
Usage Scenario
- For the VSI that adopts the static member discovery mechanism, you need to manually specify the peer address for the VSI.
- In HVPLS networking, you need to configure spoke PWs. You can configure the upe keyword in the peer command to create a UPE peer. If the specified peer is a UPE, the peer is on the user side, which does not comply with split horizon. Split horizon: The data packets received from the PW on the public network are not forwarded to other PWs, but only forwarded to the private network. On a VPLS network, full mesh and split horizon are used to avoid loops. HVPLS partitions the network, and the devices of different levels forward data to each other without complying with the split horizon rule.
- In VPWS accessing VPLS networking, you can adopt one of the following configurations to create a PW:
- Configure the VSI ID to be the same as the VC ID of the peer
- Set negotiation-vc-id to be the same as the VC ID of the peer VPWS PW. If the specified negotiation-vc-id value is different from vsi-id configured using the vsi-id command, you still need to specify negotiation-vc-id when running the undo peer command to delete the peer of the VSI. Otherwise, the peer of the VSI cannot be deleted.
- On a network where PW redundancy is configured, if the primary PW fails, traffic is switched to the secondary PW. If the secondary PW is in the standby state, service traffic cannot be forwarded, resulting in packet loss. If the ignore-standby-state parameter is configured for the PW on dual-homing PEs, the PW will ignore the standby state sent from the peer and stays in the forwarding state. This configuration can prevent packet loss during a primary/secondary PW switchover.
- A secondary PW can be created to protect the primary PW. When the primary PW fails, traffic can be immediately switched to the secondary PW, preventing traffic interruption. Note the following when you specify the secondary PW:
- The primary PW of the same VSI must exist and be unique, and the primary PW is not configured on a static UPE.
- After secondary is configured in the peer command, the number of PWs that can be configured for the VSI is restricted. If the secondary PW is configured for a VSI, that VSI can have only two PWs, the primary PW and the secondary PW.
- To change the primary or secondary attribute of a PW, you need to delete the PW and then reconfigure it. In addition, the primary/secondary attribute specified in the undo peer command must be consistent with the attribute configured for the PW. Before deleting the primary PW, delete the secondary PW of the same VSI first (if there is any).
- On a PBB VPLS network where PW redundancy is configured, multiple I-VSIs are bound to a B-VSI, and ignore-standby-state is not used during PW configuration, the primary/secondary PW switchover relies on protocol convergence when the primary PW fails.
- In the scenario where a PW interworks with an EVPN anycast VTEP in active-active mode, as shown in Figure 6 Splicing active/standby PWs with an EVPN anycast VXLAN in Feature Description, PE2 and PE3 are dual-homed to PE1 over a VPLS network, PE2 and PE3 work in active/standby mode. Assume that PW1 is the active PW and PW2 is the standby PW. PE4 is dual-homed to PE2 and PE3, which work in active-active mode. PE2 and PE3 use a virtual anycast VTEP address to establish an anycast VXLAN tunnel with PE4. A bypass VXLAN tunnel is established between PE2 and PE3 to forward traffic in case of a link fault. The bypass VXLAN tunnel works in hub PW mode, whereas the anycast VXLAN tunnel works in spoke PW mode. PW1 and PW2 are common VPLS PWs, and they are hub PWs by default. In this case, PW1 does not process traffic forwarded by the bypass VXLAN tunnel. If PW1 is configured to work in spoke PW mode using the peer upe command, PW1 does not process traffic forwarded through the anycast VXLAN tunnel. To enable PW1 to process traffic sent by both the anycast VXLAN tunnel and bypass VXLAN tunnel, run the peer ac-mode command to set PW1 to the AC mode.
Prerequisites
- LDP sessions have been set up between all the PEs to fully mesh PEs on a VPLS network through PWs.
- The VSI ID has been set in the VSI-LDP view.
- The peer [ negotiation-vc-id ] pw command can be used to create the PW view only after the peer [ negotiation-vc-id ] [ tnl-policy ] command has been run to specify the IP address of the peer.
Configuration Impact
- Specifying the peer address means manually specifying the members in a VPLS domain.
- The execution of the undo peer command will interrupt traffic of the peer. Exercise caution when using this command.
Precautions
A VPLS network is a point-to-multipoint L2VPN and therefore multiple peers can be specified for one VSI.

peer preference
Function
The peer preference command adds a specified PW to a PW protection group and specifies the priority of the PW.
The undo peer command deletes a specified PW from a PW protection group.
By default, no PW is added to a PW protection group.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Format
peer peer-address [ negotiation-vc-id vc-id ] preference preference-value
undo peer peer-address [ negotiation-vc-id vc-id ]
Parameters
| Parameter | Description | Value |
|---|---|---|
| peer-address |
Specifies the IPv4 address of the VSI peer. Generally, the loopback address of the peer is used. |
The value is in dotted decimal notation. |
| negotiation-vc-id vc-id |
Specifies the parameter negotiated with the peer. By default, the VSI ID is used. Generally, this parameter is used in VPLS accessing VLL scenarios in which the VSI IDs of the two ends are inconsistent but the two ends are required to communicate. |
The value is an integer that ranges from 1 to 4294967295. vc-id cannot be the same as any other local VSI IDs or any other VSI IDs specified by negotiate-vc-id on the local end. That is, vc-id must be an unused one. If negotiate-vc-id is configured on the local end, negotiate-vc-id or vsi-id configured on the peer end must be the same as negotiate-vc-id configured on the local end. |
| preference-value |
Specifies the priority of a peer specified when the peer is added to a PW protection group. The smaller the value, the higher the priority. Between the two peers added to a PW protection group, the one with the higher priority serves as the primary PW. |
The value is an integer that ranges from 1 to 32. |
Usage Guidelines
Usage Scenario
After creating a PW protection group and specifying the protection mode for the group, you can add specified PWs to the group for them to work in backup mode.
Master/Slave mode: specifies the priority of a peer when the peer is added to a PW protection group. A smaller value indicates a higher priority, and the PW for the peer with the highest priority becomes the primary PW. Independent mode: determines the PW priority through signaling negotiation. 1. If the two local PWs are in different states (one is up and the other is down), the PW in the up state is preferentially selected as the primary PW. 2. If the remote device does not notify the PW role, the primary and secondary PWs are selected based on the priority configuration. 3. If the remote device notifies the primary role of a PW, the PW is preferentially selected as the primary PW. If the remote device notifies the secondary role of a PW, the PW is preferentially selected as the secondary PW.Prerequisites
A PW protection group has been created, and the protection mode has been specified.
Configuration Impact
Master/Slave mode: If you first add a PW with a lower priority to a PW protection group, a PW switchover will occur when you later add the other PW with a higher priority to the group.
Independent mode: If the remote device does not notify the PW role, the primary and secondary PWs are selected based on the priority configuration. If you first add a PW with a lower priority to a PW protection group, a PW switchover will occur when you later add the other PW with a higher priority to the group.Precautions
Add PWs to a PW protection group in descending order of PW priorities. Do not add the PW with a lower priority to the PW protection group first.

Parameters
| Parameter | Description | Value |
|---|---|---|
| peer-address |
Specifies the IPv4 address of a peer. Generally, peer-address is a loopback address of the peer and does not need to be consistent with the destination address of the tunnel. |
The address is in dotted decimal notation |
| pw pw-name |
Specifies the name of a PW, which is used to distinguish the PW from other PWs. The PW name must be unique in a VSI, but can be the same as a PW name in other VSIs. |

If negotiate-vc-id is configured on the local end, negotiate-vc-id or vsi-id configured on the peer end must be the same as negotiate-vc-id configured on the local end. |
Usage Guidelines
Usage Scenario
- For the VSI that adopts the static member discovery mechanism, you need to manually specify the peer address for the VSI.
- To configure a spoke PW on the HVPLS network, you can configure upe in the peer command. If the specified peer is a UPE, the peer is on the user side, which does not comply with split horizon. In a split horizon scenario, the data packets received from the PW at the PSN side are not forwarded to other PWs. Instead, they are forwarded to the private network. On a VPLS network, full mesh and split horizon are used to prevent loops. HVPLS partitions the network, and the devices of different levels forward data to each other without complying with the split horizon principle.
- To configure a VPWS accessing VPLS network, you can adopt one of the following configurations to create a PW:
- Configuring the VSI ID to be the same as the VC ID of the peer
- Configuring the value of negotiation-vc-id vc-id to be the same as the VC ID of the peer If the value of negotiation-vc-id vc-id is different from the value of vsi-id specified in the vsi-id command, you have to configure negotiation-vc-id vc-id when running the undo peer command to delete the VSI peer. Otherwise, the VSI peer cannot be deleted.
- On a network where PW redundancy is configured, when the primary PW fails, traffic is switched to the secondary PW. If the secondary PW is in the backup state, traffic cannot be forwarded, resulting in packet loss. If ignore-standby-state is configured for the PWs on the dual-homed PEs, the secondary PW will ignore the secondary state indicated by the peer and be always in the forwarding state, preventing packet loss during a primary/secondary PW switchover.
- On a PBB VPLS network where PW redundancy is configured, multiple I-VSIs are bound to a B-VSI, and ignore-standby-state is not used during PW configuration, the primary/secondary PW switchover relies on protocol convergence when the primary PW fails.
- The secondary PW can be created to protect the primary PW. When the primary PW fails, traffic can be immediately switched to the secondary PW, preventing traffic interruption.
Note the following when you specify the secondary PW:
- The primary PW of the same VSI must exist and be unique, and the primary PW is not configured on a static U-PE.
- After secondary is configured in the peer command, the number of PWs that can be configured for the VSI is restricted. If the secondary PW is configured for a VSI, that VSI can have only two PWs, the primary PW and the secondary PW.
- To change the primary or secondary state of a PW, you need to delete the PW and then reconfigure it. In addition, the state parameter specified in the undo peer command must be consistent with the configured state of the PW.
- Before deleting the primary PW, delete the secondary PW of the same VSI.
- In a network on which PWs and an EVPN anycast VTEP interwork and the interworking points (PE2 and PE3) work in active-active mode, PE1 is dual-homed to PE2 and PE3 through a VPLS network. PE2 and PE3 work in master/backup mode, and assume that PW1 is the primary PW and PW2 is the secondary PW. PE2 and PE3 work in active-active mode when PE4 is dual-homed to them. PE2 and PE3 use a virtual anycast VTEP address to establish an anycast VXLAN tunnel with PE4. A bypass VXLAN tunnel is established between PE2 and PE3 to forward traffic in case of a link fault. The bypass VXLAN tunnel works in Hub PW mode, whereas the anycast VXLAN tunnel works in Spoke PW mode. PW1 and PW2 are common VPLS PWs, and they are Hub PWs by default. In this case, PW1 does not process traffic forwarded by the bypass VXLAN tunnel. If PW1 is configured as a Spoke PW using the peer peer-address upe command, PW1 does not process traffic forwarded by the anycast VXLAN tunnel. To enable PW1 to process traffic sent by both anycast VXLAN tunnel and bypass VXLAN tunnel, run the peer peer-address ac-mode command to set PW1 to AC mode.
Prerequisites
- LDP sessions have been set up between all the PEs to fully mesh PEs on a VPLS network through PWs.
- The VSI ID has been set in the VSI-LDP view.
- The peer peer-address [ negotiation-vc-id vc-id ] pw pw-name command can be used to create the PW view only after the peer peer-address [ negotiation-vc-id vc-id ] [ tnl-policy policy-name ] command has been run to specify the IP address of the peer.
Configuration Impact
- Specifying the peer address means manually specifying the members in a VPLS domain.
- The execution of the undo peer command will interrupt traffic of the peer. Exercise caution when using this command.

| backup-block-all |
Blocks multicast PW traffic forwarding. |
- |
Usage Guidelines
Usage Scenario
In a VLL accessing VPLS+VXLAN scenario where independent PW redundancy is configured, the PW redundancy mechanism determines the active/standby status of PWs based on the master/backup status of the remote PEs in the mVRRP group.
- The initial status of each PW between the local and remote PEs is active.
- The mVRRP group determines the master/backup status of the two remote PEs.
After the peer track admin-vrrp vrid command is configured, the PW redundancy mechanism determines the active/standby status of a PW based on the master/backup status of the corresponding remote PE in the mVRRP group.
Precautions
Only a BD VSI allows service PWs to be bound to an mVRRP group.

The value is a string of 1 to 15 case-sensitive characters, spaces and hyphens (-) not supported. The string can contain spaces if it is enclosed in double quotation marks ("). |
Usage Guidelines
Usage Scenario
Multiple PWs can be created in a VSI, every two PWs can form a protection group to protect each other.
You can create multiple PW protection groups for a VSI. After you add two PWs to a PW protection group, the two PWs will work in backup mode.Prerequisites
The VSI ID has been configured.
Follow-up Procedure
After creating PW protection groups, configure the PW redundancy mode of each PW protection group, add PWs to these groups, and configure revertive switching policies for these groups.
protect-mode pw-redundancy
Function
The protect-mode pw-redundancy command specifies the PW redundancy mode for a PW protection group.
The undo protect-mode command deletes the PW redundancy mode of a PW protection group.
By default, a PW protection group does not have a PW redundancy mode.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Parameters
| Parameter | Description | Value |
|---|---|---|
| master |
Specifies the PW redundancy mode of a PW protection group as master/slave. |
- |
| independent |
Specifies the PW redundancy mode of a PW protection group as independent. |
- |
Usage Guidelines
Usage Scenario
A PW protection group protects PWs in pairs in a VSI. After the PW protection group is configured, you must specify the protection mode. Currently, only PW redundancy is supported. PW redundancy has two modes: master/slave and independent. The PW redundancy mode must be specified when PW redundancy is used:
- In master/slave mode, a UPE determines the active/standby status of PWs. This mode applies to scenarios in which the PW status cannot be determined by remote signaling, such as HVPLS scenarios and VPLS accessing VPWS scenarios. In these scenarios, a bypass PW must also be configured.
- In independent mode, the PW status is determined by the remote signaling. This mode applies to VPLS accessing VLL scenarios in which a CE is dual-homed to two PEs between which E-Trunk/mVRRP is configured.
Prerequisites
The VSI ID and PW protection group have been configured.
Configuration Impact
If the PW redundancy mode of a PW protection group is master/slave, the local UPE determines the active/standby status of PWs based on local configurations.
Follow-up Procedure
Configure a revertive switching policy for the PW protection group and add PWs to the group.
Precautions
After a PW protection group is configured, you must specify the PW redundancy mode before configuring other parameters. Deleting the PW redundancy mode of a PW protection group will clear all the configurations of the group.
Example
<HUAWEI> system-view [HUAWEI] mpls [HUAWEI-mpls] quit [HUAWEI] mpls l2vpn [HUAWEI-l2vpn] quit [HUAWEI] vsi vsi1 [HUAWEI-vsi-vsi1] pwsignal ldp [HUAWEI-vsi-vsi1-ldp] vsi-id 100 [HUAWEI-vsi-vsi1-ldp] protect-group group1 [HUAWEI-vsi-vsi1-ldp-protect-group-group1] protect-mode pw-redundancy master

Parameters
| Parameter | Description | Value |
|---|---|---|
| clear |
Restores the default configuration. |
- |
| manual |
Forcibly performs an active/standby PW switching. |
- |
Usage Guidelines
Usage Scenario
If you want to maintain the device where the primary PW in a PW protection group resides, you must run the protect-switch manual command to switch traffic from the primary PW to the secondary PW first. After the device where the primary PW resides stabilizes, run the protect-switch clear command to switch traffic back from the secondary PW to the primary PW.
Prerequisites
A PW protection group has been created, and the PW redundancy mode has been configured as master/slave. The primary and secondary PWs have been added to the PW protection group and their status is Up.
Configuration Impact
After you run the protect-switch manual command, traffic switches from the primary PW to the secondary PW. After you run the protect-switch clear command, traffic switches from the secondary PW to the primary PW.
Precautions
The interval between running the protect-switch manual and protect-switch clear commands must be longer than 15s.
Example
<HUAWEI> system-view [HUAWEI] mpls [HUAWEI-mpls] quit [HUAWEI] mpls l2vpn [HUAWEI-l2vpn] quit [HUAWEI] vsi vsi1 [HUAWEI-vsi-vsi1] pwsignal ldp [HUAWEI-vsi-vsi1-ldp] vsi-id 100 [HUAWEI-vsi-vsi1-ldp] protect-group group1 [HUAWEI-vsi-vsi1-ldp-protect-group-group1] protect-switch manual
pw (VSI-LDP view)
Function
The pw command displays the PW view.
The undo pw command deletes the PW view.
By default, the PW view is not displayed.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Parameters
| Parameter | Description | Value |
|---|---|---|
| pw pw-name |
Specifies the name of a PW. |
The value is a string of 1 to 15 case-sensitive characters, spaces not supported. The string can contain spaces if it is enclosed in double quotation marks ("). |
Usage Guidelines
Usage Scenario
To enter the PW view, run the pw command.
Prerequisites
A PW view has been created using the peer peer-address [ negotiation-vc-id vc-id ] pw pw-name command.
Precautions
The PW name must be unique in a VSI, but can be the same as a PW name in other VSIs.
Example
<HUAWEI> system-view [HUAWEI] mpls [HUAWEI-mpls] quit [HUAWEI] mpls l2vpn [HUAWEI-l2vpn] quit [HUAWEI] vsi aa static [HUAWEI-vsi-aa] pwsignal ldp [HUAWEI-vsi-aa-ldp] vsi-id 1 [HUAWEI-vsi-aa-ldp] peer 1.1.1.1 [HUAWEI-vsi-aa-ldp] peer 1.1.1.1 pw pw1 [HUAWEI-vsi-aa-ldp-pw-pw1] quit [HUAWEI-vsi-aa-ldp] pw pw1
pw spoke-mode
Function
The pw spoke-mode command configures the PWs of a BGP AD VSI as spoke PWs.
The undo pw spoke-mode command restores the default configuration.
By default, the PWs of a BGP AD VSI are hub PWs.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Usage Guidelines
Usage Scenario
If a BGP AD VPLS needs to be deployed on a network with a star or tree topology (on which one PE that serves as a server or an authorization device is configured as the Hub-PE, and other PEs are configured as Spoke-PEs) the PWs of the VSI on the Hub-PE must be configured as spoke PWs using the pw spoke-mode command to disable split horizon of the PWs.
Prerequisites
The vpls-id command has been run in the VSI-BGPAD view to specify a VPLS ID.
Configuration Impact
After the pw spoke-mode command is run, all PWs of the specified VSI become spoke PWs. Split horizon does not function on spoke PWs. This means that packets sent from spoke PWs can be forwarded to other PWs. If the undo pw spoke-mode command is run, all PWs of the VSI will be changed to hub PWs that abide by split horizon rules.
Precautions
The pw spoke-mode command takes effect on all the PWs of a BGP AD VSI.
Example
<HUAWEI> system-view [HUAWEI] mpls [HUAWEI-mpls] quit [HUAWEI] mpls l2vpn [HUAWEI-l2vpn] quit [HUAWEI] vsi company1 [HUAWEI-vsi-company1] bgp-ad [HUAWEI-vsi-company1-bgpad] vpls-id 65535:1 [HUAWEI-vsi-company1-bgpad] pw spoke-mode

Usage Guidelines
Usage Scenario
After creating a VSI, you must specify the signaling mode for the VSI before performing other configurations.
Prerequisites
A VSI has been created or the VSI view is displayed using the vsi vsi-name command.
Configuration Impact
After the signaling mode is specified for a VSI, the VSI uses LDP or BGP to negotiate VPN labels and establish PWs.
Follow-up Procedure
After you run this command to enter the VSI-LDP or VSI-BGP view, you also need to set the VSI ID and specify the VSI peer to complete the VSI configuration.

Parameters
| Parameter | Description | Value |
|---|---|---|
| ldp |
Indicates that the VSI uses the LDP signaling for negotiation and PW establishment. A VSI that uses the static member discovery mechanism must use the LDP signaling. |
- |
Usage Guidelines
Usage Scenario
After creating a VSI, you must specify the signaling mode for the VSI before performing other configurations.
Configuration Impact
After LDP is specified as the signaling mode for a VSI, the VSI negotiates private network labels and sets up a PW based on the LDP signaling.
Follow-up Procedure
After you run this command to enter the VSI-LDP or VSI-BGP view, you also need to set the VSI ID and specify the VSI peer to complete the VSI configuration.
reroute
Function
The reroute command configures a revertive switching policy for a PW protection group with the master/slave PW redundancy mode.
The undo reroute command deletes the revertive switching policy for a PW protection group with the master/slave PW redundancy mode.

The value is an integer ranging from 10 to 10800, in seconds. The default value is 30s. |
| immediately |
Indicates that the revertive switching policy is immediate switchback. |
- |
| never |
Indicates that the revertive switching policy is non-revertive. Traffic is not switched back to the primary PW even after the primary PW recovers. Traffic will be switched back to the primary PW only when the secondary PW fails. |
- |
Usage Guidelines
Usage Scenario
The reroute command can configure revertive switching policies for only PW protection groups with the master/slave PW redundancy mode. The revertive switching policy for PW protection groups with the independent PW redundancy mode is immediate switchback and cannot be modified.
Currently, three types of revertive switching policies are available:- Delayed switchback: Traffic is switched back to the primary PW after the delay time specified by delay-time. After the switching is performed, a UPE notifies the remote PE on the secondary PW of a fault. On a large-scale network, packet loss caused by incomplete route convergence may occur during the switchback. To prevent this problem, configure traffic to be switched back after a delay.
- Immediate switchback: Traffic is immediately switched back to the primary PW. This revertive switching policy applies to scenarios in which users hope traffic to be restored as soon as possible.
- Non-revertive: Traffic will not be switched back to the primary PW even after the primary PW recovers. Traffic will be switched back to the primary PW only when the secondary PW fails. If you do not want traffic to be frequently switched between the primary and secondary PWs, use the non-revertive policy.
Prerequisites
The PW redundancy mode of the PW protection group has been configured as master/slave.
Configuration Impact
The revertive switching policy determines the switchback behavior of the traffic after the primary PW recovers.
Example

Specifies an RD for a VSI. |
The available RD formats are as follows:
|
Usage Guidelines
Usage Scenario
On a BGP VPLS network, after creating a VSI, you must configure an RD for the VSI to identify the VSI on a PE.
Prerequisites
The VSI-BGP view has been displayed using the pwsignal bgp command.
Configuration Impact
After an RD is configured for a VSI, you can directly modify the RD.
Precautions
- On a PE, you need to configure different RDs for different VSIs.
- VSIs with the same ID on different PEs can have either the same RD or different RDs.
Example

Usage Guidelines
Usage Scenario
During service management, for example, service debugging or service halting, you can disable a VSI temporarily, and then add, cancel, or adjust VSI functions.
The shutdown command mainly affects the PW connections of a VSI. After the command is run, the AC is Down and the Layer 2 forwarding table is deleted.Configuration Impact
After a VSI is disabled, the VSI cannot forward packets and withdraws all PW labels.
Precautions
After a VSI is disabled, packets cannot be forwarded. Therefore, exercise caution when running this command.
site
Function
The site command configures a site ID for a VSI.
The undo site command deletes the site ID of a VSI.
By default, no site ID is configured for a VSI.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Parameters
| Parameter | Description | Value |
|---|---|---|
| siteId |
Specifies a site ID. |
The value is an integer ranging from 0 to 65534. |
| range site-range |
Specifies the number of sites in a VSI. |
The value is an integer ranging from 1 to 65535. The default value is 10. |
| default-offset offsetValue |
Specifies the offset value of the initial site ID in a VSI. |
The value is 0 or 1. The default value is 0. |
Usage Guidelines
Usage Scenario
On a BGP VPLS network, after configuring an RD for a VSI, you must configure a site ID for the VSI to calculate VC labels for PWs.
Prerequisites
An RD has been configured using the route-distinguisher (VSI-BGP view) command.
Configuration Impact
In networking scenario where PE1 and PE2 are directly connected and a VSI is created on each PE separately, after the site command is configured, the information exchanged between the PEs is as follows:
- After an RD is configured for the VSI, PE1 automatically establishes a BGP session with PE2 and sends an Update message that carries the MP-REACH attribute to PE2. The MP-REACH attribute contains the site ID and label block information of PE1.
- Upon receipt of the Update message with the MP-REACH attribute, PE2 calculates a unique label as its local VC label based on its own site ID and the label block carried in the message. Then, PE2 establishes a unidirectional VC named VC1 to PE1. At the same time, PE2 calculates the VC label of PE1 based on the site ID and label block carried in the Update message and sends an Update message to PE1. Upon receipt of the message, PE1 takes similar actions as PE2 and establishes a unidirectional VC named VC2 to PE2.
Precautions
The site IDs on both ends of a VPLS PW must be different. The local site ID must be smaller than the peer's rangevalue plus default-offset, but greater than or equal to the peer's default-offset.
Example
<HUAWEI> system-view [HUAWEI] mpls [HUAWEI-mpls] quit [HUAWEI] mpls l2vpn [HUAWEI-l2vpn] quit [HUAWEI] vsi vsi1 auto [HUAWEI-vsi-vsi1] pwsignal bgp [HUAWEI-vsi-vsi1-bgp] route-distinguisher 192.168.1.1:1 [HUAWEI-vsi-vsi1-bgp] site 1 range 100
stream-dual-receiving
Function
The stream-dual-receiving command configures both the active and standby PWs in a protection group to receive packets.
The undo stream-dual-receiving command restores the default configuration.
By default, the standby PW cannot receive packets.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Usage Guidelines
Usage Scenario
On a network that has PW redundancy configured, to prevent packet loss during a traffic switchback, run the stream-dual-receiving command on a single-homing PE to configure both the active and standby PWs in a protection group to receive packets.
If this command is not run, only the active PW can receive packets. After the primary PW recovers and a traffic switchback is triggered, the secondary PW on the single-homing PE becomes the standby PW and the PE notifies the peer of the status change. As there is a delay in signaling transmission, before the peer PE receives the signaling packet, the peer PE still sends packets along the secondary PW. After the single-homing PE receives packets from the secondary PW, the PE discards the packets.Prerequisites
The primary and secondary PWs have been configured.
Precautions
This command can be run only when both the primary and secondary PWs exist.
Example
<HUAWEI> system-view [HUAWEI] mpls [HUAWEI-mpls] quit [HUAWEI] mpls l2vpn [HUAWEI-l2vpn] quit [HUAWEI] vsi test [HUAWEI-vsi-test] pwsignal ldp [HUAWEI-vsi-test-ldp] vsi-id 100 [HUAWEI-vsi-test-ldp] protect-group GroupA [HUAWEI-vsi-test-ldp-protect-group-GroupA] protect-mode pw-redundancy master [HUAWEI-vsi-test-ldp-protect-group-GroupA] stream-dual-receiving
tnl-policy (VSI view)
Function
The tnl-policy command configures a VSI to reference a tunnel policy.
The undo tnl-policy command restores the default configuration.
By default, no tunnel policy is configured for a VSI.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Parameters
| Parameter | Description | Value |
|---|---|---|
| policy-name |
Specifies the name of a tunnel policy. |
The value is a string of 1 to 39 case-sensitive characters without spaces. |
Usage Guidelines
Usage Scenario
By default, VPLS forwards packets over LDP LSPs on the public network, and load balancing is performed if there are more than one LDP LSP to the same destination address.
If you want to change the type of the public network tunnel used for packet forwarding or if you want to enable load balancing among multiple tunnels, you can run the tunnel-policy command in the system view to configure a tunnel policy and the tnl-policy command in the VSI view to reference this tunnel policy.Prerequisites
The tunnel policy to be referenced has been created.
Configuration Impact
- After a tunnel policy is referenced, the VPLS traffic is forwarded on the public network using the tunnel specified in the tunnel policy.
- The undo tnl-policy command restores the default tunnel (LDP LSP) used for packet forwarding.
Precautions
In addition to running this command to reference a tunnel policy, you can run the peer command in the VSI view to specify the peer address and the tunnel policy to be referenced by the VSI. The tunnel policy specified in the peer command has a higher priority than that specified in the tnl-policy command in the VSI view. If tunnel policies are specified in both the tnl-policy and peer commands, the tunnel policy specified in the peer command is preferred.
track admin-vsi
Function
The track admin-vsi command binds a service VSI to the specified mVSI.
The undo track admin-vsi command deletes the binding between a service VSI and the specified mVSI.
By default, a service VSI is not bound to any mVSI.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Parameters
| Parameter | Description | Value |
|---|---|---|
| vsi-name |
Specifies the name of a VSI. |
The value is a string of 1 to 31 case-sensitive characters, spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string. |
Usage Guidelines
The track admin-vsi command applies only to LDP VPLS. You must run the pwsignal and vsi-id commands before running the track admin-vsi command.
The track admin-vsi command can be used only in the service VSI. A service VSI can be bound only to one mVSI. To prevent the service VSI from encountering routing loops in an STP over PW scenario, run this command.Example
<HUAWEI> system-view [HUAWEI] mpls [HUAWEI] mpls l2vpn [HUAWEI-l2vpn] quit [HUAWEI] vsi v100 static [HUAWEI-vsi-v100] pwsignal ldp [HUAWEI-vsi-v100-ldp] vsi-id 100 [HUAWEI-vsi-v100-ldp] quit [HUAWEI-vsi-v100] admin-vsi [HUAWEI-vsi-v100] quit [HUAWEI] vsi v200 static [HUAWEI-vsi-v200] pwsignal ldp [HUAWEI-vsi-v200-ldp] vsi-id 200 [HUAWEI-vsi-v200-ldp] quit [HUAWEI-vsi-v200] track admin-vsi v100
track hub-pw
Function
The track hub-pw command associates the spoke PW status with the hub PW status.
The undo track hub-pw command deletes the association between the spoke PW status and the hub PW status.
By default, the spoke PW status is not associated with the hub PW status.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Usage Guidelines
Figure 1 shows the association between spoke PW and hub PW in the configuration guide, the UPE connects to SPE1 over PW1, a primary PW, and connects to SPE2 over PW2, a secondary PW. PW1 and PW2 work in backup mode. SPEs and NPEs are connected using hub PWs.
Under normal circumstances, if all hub PWs connected to SPE1 go Down but PW1 is Up, the upstream traffic still travels along the primary PW, PW1. As a result, traffic gets lost. To prevent traffic loss, run the track hub-pw command on SPE1 to associate the spoke PW status with the hub PW status. After the track hub-pw command is run, SPE1 instructs the UPE to switch traffic to the secondary spoke PW after detecting that all connected hub PWs go Down.Example
<HUAWEI> system-view [HUAWEI] mpls [HUAWEI-mpls] quit [HUAWEI] mpls l2vpn [HUAWEI-l2vpn] quit [HUAWEI] vsi vsi1 [HUAWEI-vsi-vsi1] pwsignal ldp [HUAWEI-vsi-vsi1-ldp] vsi-id 100 [HUAWEI-vsi-vsi1-ldp] peer 2.2.2.2 upe [HUAWEI-vsi-vsi1-ldp] peer 2.2.2.2 pw 1 [HUAWEI-vsi-vsi1-ldp-pw-1] track hub-pw
traffic-statistics enable (VSI-BGPAD view)
Function
The traffic-statistics peer enable command enables VSI-based global traffic statistics collection for BGP AD VPLS PWs.
The undo traffic-statistics peer enable command disables VSI-based global traffic statistics collection for BGP AD VPLS PWs.
By default, VSI-based global traffic statistics collection is disabled for BGP AD VPLS PWs.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Usage Guidelines
Usage Scenario
After a BGP AD VPLS network is configured, if you want to view traffic statistics about all BGP AD PWs in a specified VSI to learn the network running status, you can run this command to enable global traffic statistics collection for all BGP AD VPLS PWs in the specified VSI.
Prerequisites
A VPLS ID has been specified in the VSI-BGP AD view.
Precautions
If the traffic-statistics enable and traffic-statistics peer commands are both run in the VSI-BGP AD view, configuration of the traffic-statistics peer command takes effect on the peer.
Example
<HUAWEI> system-view [HUAWEI] mpls [HUAWEI-mpls] quit [HUAWEI] mpls l2vpn [HUAWEI-l2vpn] quit [HUAWEI] vsi company1 [HUAWEI-vsi-company1] bgp-ad [HUAWEI-vsi-company1-bgpad] vpls-id 100:1 [HUAWEI-vsi-company1-bgpad] traffic-statistics enable
traffic-statistics enable (VSI-LDP view)
Function
The traffic-statistics enable command globally enables PW traffic statistics collection in the VSI-LDP view.
The undo traffic-statistics enable command disables PW traffic statistics collection in the VSI-LDP view.
By default, PW traffic statistics collection is disabled globally in the VSI-LDP view.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Usage Guidelines
This command is used in the VSI-LDP view to globally enable PW traffic statistics collection.
The traffic-statistics peer enable command enables peer-based VPLS PW traffic statistics collection. Peer-based VPLS PW traffic statistics collection takes precedence over global VPLS PW traffic statistics collection. That is, even if you run the undo traffic-statistics enable command to disable the function to collect statistics about global VPLS PW traffic, you can still view statistics about peer-based VPLS PW traffic.
The undo traffic-statistics peer enable command clears the configuration of peer-based traffic statistics collection. After the configuration is cleared, the peer-based VPLS PW traffic statistics collection function inherits the status of the global VPLS PW traffic statistics collection function. For example, if you run the traffic-statistics enable command to enable the function to collect statistics about global VPLS PW traffic, you can also view statistics about peer-based VPLS PW traffic.traffic-statistics peer
Function
The traffic-statistics peer enable command collects statistics about public network traffic on a specified PW in a BGP AD VPLS domain.
The undo traffic-statistics peer enable command cancels the collection of statistics about public network traffic on a specified PW in a BGP AD VPLS domain.

Usage Guidelines
In the VSI-LDP view, you can enable or disable the function to collect statistics about the public traffic of the LDP VPLS PW. The PW is uniquely identified by the VSI name, the next-hop IP address, and the peer PW ID.
The traffic-statistics peer peer-address [ negotiation-vc-id vc-id ] enable command enables peer-based VPLS PW traffic statistics collection, which takes precedence over global VPLS PW traffic statistics collection. That is, even if you run the undo traffic-statistics enable command to disable global VPLS PW traffic statistics collection, you can still view peer-based VPLS PW traffic statistics.
The undo traffic-statistics peer peer-address [ negotiation-vc-id vc-id ] enable command clears the configuration of peer-based traffic statistics collection. After the configuration is cleared, peer-based VPLS PW traffic statistics collection inherits the enabling/disabling status of global VPLS PW traffic statistics collection. For example, if you run the traffic-statistics enable command to enable global VPLS PW traffic statistics collection, you can also view peer-based VPLS PW traffic statistics.Example

- |
Usage Guidelines
Usage Scenario
If a VSI cannot find the entry that matches the destination address of the received frame in the MAC address table, the frame is considered an unknown frame.
After the unknown-frame command is run, unknown frames are divided into unknown unicast frames and unknown multicast frames for processing. The processing modes include drop and broadcast. Sometimes, you are advised to set the processing mode to drop to avoid attacks or to save system resources and network bandwidth.Precautions
The unknown-frame unicast drop command discards the received unknown unicast frames and disables MAC address learning.
upe-npe mac-withdraw enable
Function
The upe-npe mac-withdraw enable command configures a network provider edge (NPE) to forward the LDP MAC Withdraw messages received from an underlayer provider edge (UPE) to other NPEs.

vpls ignore-ac-state
Function
The vpls ignore-ac-state command prevents the status of a VSI from being affected by AC status changes.
The undo vpls ignore-ac-state command restores the default configuration.
By default, a service VSI can be Up only if at least one AC interface or UPE PW is Up.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Usage Guidelines
Usage Scenario
Before the replacement of CEs, you can configure VSIs on UPEs to temporarily ignore the AC status check. Then, check whether VSIs on UPEs can work properly after new CEs are deployed. A VSI can be Up only if at least one AC interface or one UPE PW is Up. After you configure a VSI to ignore the AC status check, the VSI remains Up provided that; if one UPE PW is Up, regardless of whether the AC interface is Up or Down.
The AC status has two meanings:- Status of a physical AC interface or logical AC interface that is bound to the VSI
- UPE PW status in the scenario of VLL accessing VPLS If your want to prevent the status of all the VSIs from being affected by AC status changes, run the vpls ignore-ac-state command. If your want to prevent the status of one VSI from being affected by AC status changes, run the ignore-ac-state command.
Follow-up Procedure
After service switching, run the undo vpls ignore-ac-state command to restore the default configuration.
vpls mac-withdraw loop-detect enable
Function
The vpls mac-withdraw loop-detect enable command enables MAC withdraw loop detection.
The undo vpls mac-withdraw loop-detect enable command disables MAC withdraw loop detection.
By default, MAC withdraw loop detection is disabled.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Usage Guidelines
Usage Scenario
On a dual-homing VPLS or HVPLS network, MAC withdraw messages can be forwarded between hub and spoke PWs and between spoke PWs. Incorrect configurations may cause a MAC withdraw message loop, which results in traffic loss. If the loop involves a large number of MAC withdraw messages, denial of service (DoS) attacks may occur. To resolve these problems, run the vpls mac-withdraw loop-detect enable command to enable MAC withdraw loop detection. After you enable MAC withdraw loop detection, a PE immediately discards MAC withdraw messages when it detects a MAC withdraw message loop.
Prerequisites
MPLS L2VPN has been enabled using the mpls l2vpn command.
vpls-id
Function
The vpls-id command specifies the VPLS domain to which a VSI belongs.
The undo vpls-id command disables the specified VPLS domain to which a VSI belongs.

This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Parameters
| Parameter | Description | Value |
|---|---|---|
| vplsIdValue |
Specifies a VPLS domain to which multiple VSIs on PEs belong. |
A VPLS ID is in one of the following formats:
|
Usage Guidelines
Usage Scenario
VSIs in a BGP AD VPLS domain use BGP signaling to automatically discover members in the same VPLS domain. A VPLS domain is uniquely identified by a VPLS ID. When creating BGP AD VSIs on different PEs, specify the same VPLS ID for the VSIs so that they can join the same VPLS domain. When creating multiple BGP AD VSIs on a PE, specify different VPLS IDs for the VSIs to allow them to join different VPLS domains. To change the VPLS ID of a VSI, you need to delete the VSI and then recreate it and configure its VPLS ID.
Prerequisites
The bgp-ad command has been run in the VSI view to configure automatic VPLS member discovery and PW deployment for the current VSI and to display the VSI-BGP AD view.
Configuration Impact
A VPLS ID will be specified for the BGP AD VSI after the vpls-id command is run, and the VPLS ID cannot be specified for the other BGP AD VSIs on the same PE.
Precautions
A BGP AD VPLS domain is uniquely identified by a VPLS ID. The VSIs on a PE must be configured with different VPLS IDs. The VSIs that belong to the same VPLS domain and reside on different PEs must be configured with the same VPLS ID.
After a VPLS ID is configured for a VSI, it cannot be directly changed. To change the VPLS ID, you need to delete the VSI and then recreate the VSI.Example
<HUAWEI> system-view [HUAWEI] mpls [HUAWEI-mpls] quit [HUAWEI] mpls l2vpn [HUAWEI-l2vpn] quit [HUAWEI] vsi company2 [HUAWEI-vsi-company2] bgp-ad [HUAWEI-vsi-company2-bgpad] vpls-id 2.2.2.2:1

- |
| import-extcommunity |
Specifies the VPN target carried in imported routes. |
- |
| export-extcommunity |
Specifies the VPN target carried in exported routes. |
- |
| all |
Deletes all VPN targets. |
- |
Usage Guidelines
VPN targets are used on a BGP VPLS network to control route advertisement and communication between nodes:
- A PE adds export VPN targets to routes to be advertised to other PEs.
- After a PE receives routes from other PEs, it determines whether to import the received routes to local VSIs by comparing the export VPN targets of these routes with the local import VPN targets.
Example
<HUAWEI> system-view [HUAWEI] mpls [HUAWEI-mpls] quit [HUAWEI] mpls l2vpn [HUAWEI-l2vpn] quit [HUAWEI] vsi vsi1 auto [HUAWEI-vsi-vsi1] pwsignal bgp [HUAWEI-vsi-vsi1-bgp] route-distinguisher 1:1 [HUAWEI-vsi-vsi1-bgp] vpn-target 100:100 import-extcommunity [HUAWEI-vsi-vsi1-bgp] vpn-target 200:200 export-extcommunity
vpn-target (VSI-BGPAD view)
Function
The vpn-target command associates a VSI in a BGP AD VPLS domain with one or more VPN targets.
The undo vpn-target command deletes the association between a VSI and VPN targets.
By default, a VSI is not associated with any VPN target. The association must be configured when a VSI is created.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Format
vpn-target { vpnTargetValue } &<1-16> [ both | import-extcommunity | export-extcommunity ]
undo vpn-target { all | { vpnTargetValue } &<1-16> } [ both | import-extcommunity | export-extcommunity ]
Parameters
| Parameter | Description | Value |
|---|---|---|
| vpnTargetValue |
Associates a VPN target with a VSI. |
The format of a VPN target can be one of the following:
|
| both |
Specifies the extended community attributes of the received and sent routing information. |
- |
| import-extcommunity |
Receives routing information carrying specified extended community attributes. |
- |
| export-extcommunity |
Specifies the extended community attributes carried in routing information to be sent. |
- |
| all |
Deletes all VPN targets. |
- |
Usage Guidelines
Usage Scenario
VPN targets can be used in a BGP AD VPLS domain to control the route advertisement and communication between nodes. When a PE advertises routing information to other PEs of different VSIs, it adds export VPN targets to the routing information. When the PE receives routing information from other PEs, it uses import VPN targets to determine whether to import the routing information to the VSIs on it.
Prerequisites
A VPLS ID has been configured for the VSI.
Configuration Impact
After the vpn-target command is run, the PE only advertises the routing information that contains the export VPN targets and imports the routing information that contains the import VPN targets. Two PEs are allowed to communicate with each other only when the VPN targets carried in their exchanged routing information match.
Precautions
A PW can be set up between two VSIs in a BGP AD VPLS domain only when the import VPN target associated with a VSI is the same as the export VPN target associated with the other VSI.
Example
<HUAWEI> system-view [HUAWEI] mpls [HUAWEI-mpls] quit [HUAWEI] mpls l2vpn [HUAWEI-l2vpn] quit [HUAWEI] vsi company2 [HUAWEI-vsi-company2] bgp-ad [HUAWEI-vsi-company2-bgpad] vpls-id 100:1 [HUAWEI-vsi-company2-bgpad] vpn-target 3:3 export-extcommunity [HUAWEI-vsi-company2-bgpad] vpn-target 4:4 import-extcommunity [HUAWEI-vsi-company2-bgpad] vpn-target 5:5 both
vsi (System view)
Function
The vsi command creates a VSI or displays the VSI view.
The undo vsi command deletes a VSI.
By default, no VSI is created.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Parameters
| Parameter | Description | Value |
|---|---|---|
| vsi-name |
Name of a VSI instance. |
The value is a string of 1 to 31 case-sensitive characters, spaces not supported. The VSI names on one device must be different. The string can contain spaces if it is enclosed in double quotation marks ("). |
| static |
Uses static VPLS member discovery. |
- |
| auto |
Uses automatic VPLS member discovery. |
- |
Usage Guidelines
Usage Scenario
VSIs are essential to VPLS networks. On a device, a VSI must be created for each VPLS network.
Prerequisites
Before creating a VSI, enable MPLS L2VPN on the device.
Configuration Impact
- After a VSI is configured for a VPLS network, the VPLS packets are forwarded based on the VSI.
- The execution of the undo vsi command interrupts VPLS traffic. Exercise caution when using this command.
Follow-up Procedure
After creating a VSI, you need to specify the signaling mode and set the VSI ID and peer address to complete the VPLS configuration.
Precautions
On a VPLS network:
- You can configure different names for the VSIs on different devices.
- You must configure a unique VSI ID for each VSI on a device. The VSI and VSI ID has a one-to-one mapping relationship.
- You can specify multiple peers for a VSI on a device. If a VSI has been bound to an AC interface, deleting the VSI causes all configurations in the VSI to be deleted and the binding relationship to be removed. Therefore, exercise caution when performing this operation.
Example
<HUAWEI> system-view [HUAWEI] mpls lsr-id 1.1.1.1 [HUAWEI] mpls [HUAWEI-mpls] quit [HUAWEI] mpls l2vpn [HUAWEI-l2vpn] quit [HUAWEI] vsi company1

vsi-id
Function
The vsi-id command sets a VSI ID.
The undo vsi-id command deletes a VSI ID.
By default, no VSI ID is set for a VSI.
This command is supported only on the S6780-H, S6730-H-V2, S5755-H, S5732-H-V2, S6750-S and S6750-H.
Parameters
| Parameter | Description | Value |
|---|---|---|
| vsi-id |
Specifies the ID of a VSI. |
The value is an integer ranging from 1 to 4294967295. The VSI ID of each VSI is unique on a device. |
Usage Guidelines
Usage Scenario
If a VSI uses the LDP signaling, the VSI ID must be set.
The IDs of the VSIs in the same VPLS domain must be consistent.Configuration Impact
A VSI ID uniquely identifies a VSI. The VSIs with the same VSI ID belong to one VPLS domain.
Follow-up Procedure
You can specify a peer for the VSI only after the VSI ID is set.
Precautions
- The ID of each VSI must be unique on a device.
- If the IDs of the VSIs on the two ends of a PW are different and the peer command is run to specify the peer, you must run the negotiation-vc-id command to set the same <negotiation-vc-id> for the two ends. Otherwise, PW negotiation fails.
