Parameter Description: E-LAN Service

Parameter Description: E-LAN Service

This topic describes the parameters related to the E-LAN Service configuration.

E-LAN Service Parameters (Configuration on a Per-NE Basis)

This topic describes the parameters, such as Service ID and Service Name, for configuring an E-LAN service.

Table 3-67 lists the parameters for configuring an E-LAN service.

Table 3-67 Parameters for configuring an E-LAN service

Field

Value

Description

Service ID

For example, 11

Displays or specifies the ID of the Ethernet service.

Service Name

For example, test

Displays or specifies the name of the Ethernet service.

MTU

46-65535

Default: 1500

Specifies the maximum length of the payload in a UNI-side Ethernet packet. MTU indicates the maximum transmission unit. When the length of the received packet exceeds the specified MTU, the packet is dropped.
NOTE:
This parameter is invalid for OptiX OSN 9800.
Processing Method of Unknown Unicast Packets Flood, Discard

Default: Flood

Specifies the mode for processing unknown unicast packets. Discard means to drop the unknown unicast packets; Flood means to broadcast the unknown unicast packets on the forwarding port.
Processing Method of Unknown Multicast Packets Flood, Discard

Default: Flood

Specifies the mode for processing unknown multicast packets. Discard means to drop the unknown multicast packets; Flood means to broadcast the unknown multicast packets on the forwarding port.

Self-Learning MAC Address

Enabled, Disabled

Default: Enable

Specifies whether to enable the MAC address learning function. The MAC address learning function enables the device to learn MAC addresses to the MAC address forwarding table.

Self-Learning MAC Address can be set to Enabled or Disabled. If MAC address self-learning is enabled, the bridge automatically learns MAC addresses to generate MAC address forwarding entries and also supports the static MAC address forwarding entries that are manually configured. If MAC address self-learning is disabled, the bridge supports only the static MAC address forwarding entries that are manually configured.

MAC Address Learning Mode

IVL, SVL

Default: IVL

IVL indicates shared VLAN learning. All VLANs share a MAC address forwarding table. Each MAC address is unique in the forwarding table.

SVL indicates the independent VLAN learning. The forwarding tables for different VLANs are independent from each other. It is acceptable that the MAC address forwarding tables for different VLANs have the same MAC address.

When Tag Type is set to Tag-Transparent, the parameter value is IVL by default and is not configurable.

Ring Multicast Protection

true, false

Default: false

Specifies whether to enable the ring multicast protection function.

Tag Type

C-Awared, S-Awared, Tag-Transparent

Default: C-Awared

C-Awared indicates that the learning is based on the C-TAG (client-side VLAN tag). C-Awared indicates that the service packets with C-VLAN tags are supported.

S-Awared indicates that the learning is based on the S-TAG (operator service-layer VLAN tag). S-Awared indicates that the service packets with both C-VLAN and S-VLAN tags are supported. S-Awared is valid only when Encapsulation Type is set to QinQ for a port.

Tag-Transparent indicates that all Ethernet packets can be transmitted transparently when Encapsulation Type is set to Null for a port. Tag Transparent indicates that the service packets without VLAN tags are supported.

service Tag Role

User, Service

Default: User

Service Tag Role is used to indicate the user access mode, that is, the encapsulation mode when the Ethernet service is received by the AC.

  • User: If the service-delimiting tag is User, the user access mode is Ethernet. In this case, the Ethernet packet that the CE sends to the PE does not carry a provider-tag (P-Tag). If the packet header contains the VLAN tag, the VLAN tag is the inner VLAN tag of the user packet, which is called user-tag (U-Tag). The PE does not identify or process a U-Tag.
  • If the service-delimiting tag is Service, the user access mode is VLAN. In this case, the Ethernet packet that the CE sends to the PE carries a provider-tag (P-Tag), which is provided for the carrier to differentiate users. The PE identifies and processes a P-Tag based on the PW encapsulation mode.

Loop Detect Enable

Enabled, Disabled

Default: Enabled

Specifies whether to enable the loop detect.

If packet loopbacks occur, a broadcast storm occurs. The E-LAN service loopback detection function is provided to detect and disable the looped back service in time. The function helps prevent network congestion.

Loop Detect Block Enable

Enabled, Disabled

Default: Disabled

Specifies whether to enable the loop detect block.

You can set the enable status of automatic service loop blocking. If a service loop is found and automatic service loop blocking is enabled, E-LAN services will be automatically blocked and a service blocking alarm will be reported to the user.

Loop Detect Priority

0-6

Default: 5

Specifies the priority when multi-services are enabled the loop detect.

The 0 indicates the highest priority.

Loop Detect Vlan List

1-4094

Specifies the services VLAN for loop detect.

Field

Value

Description

Port

For example, 1(PORT-1)

Enabled Packet Suppression true, false

Default: true

Specifies whether to enable the broadcast packet suppression. Enabling the broadcast packet suppression efficiently prevents the broadcast storm and network congestion, and ensures the normal running of services.
Traffic Suppression Type Percent, AbsoluteValue -
Broadcast Packet Suppression Threshold(Kbit/s)

-

Specifies the threshold of broadcast packet suppression. The E-LAN service supports this parameter.

After broadcast packet suppression is enabled, broadcast packets are suppressed when the bandwidth occupied by broadcast packets on the port is higher than the threshold. A smaller absolute value of this parameter means that a smaller volume of broadcast traffic is allowed to pass through the port.

Broadcast Packet Suppression Threshold(%) 0-100

Default: 10

Specifies the threshold of broadcast packet suppression. The E-LAN service supports this parameter.

When the broadcast packet suppression is enabled, the broadcast packets are suppressed if the following requirement is met: Occupancy rate of the broadcast packet to the bandwidth of the current port > the total bandwidth of the port x the suppression threshold x 1%. A low occupancy rate indicates that the number of broadcast packets that pass through the port is small. If the occupancy rate is 100%, it indicates that the broadcast packets that pass through the port are not suppressed.

Unknown Unicast Packet Suppression(Kbit/s) - Specifies the threshold of unknown unicast packet suppression.
Unknown Unicast Packet Suppression(%) 0-100

Default: 10

Specifies the threshold of unknown unicast packet suppression.
Unknown Multicast Packet Suppression(Kbit/s) - Specifies the threshold of unknown multicast packet suppression.
Unknown Multicast Packet Suppression(%) 0-100

Default: 10
