Parameter Description: Ethernet Private Line Services (on a Per-NE Basis)

This topic describes the parameters related to Ethernet private line services.

E-Line Service Parameters

You need to set the parameters such as Service Name, Service ID, Direction, and Bearer Type when configuring an E-Line service.

Table 3-340 lists the parameters that are used for configuring an E-Line service.

Table 3-340  Parameters for an E-Line service

Field

Value

Description

Service ID

Example: 11

Set and query the ID of the Ethernet service.

Service Name

Example: test

Set and query the name of the Ethernet service.

Source Node

Example:3-EM6F-1 (Port-1)(14)

Display the source node of the E-Line service. The format is Slot number - Board name - Port name (VLAN ID).

Sink Node

Example: PW-0

Display the sink node of the E-Line service. The sink node can be a port, PW or QinQ Link.

Direction

UNI-UNI, UNI-NNI, NNI-NNI

In the case of the UNI-NNI direction, select the network-side bearer type as PW Port or QinQ Link.

Service Tag Role

User, Service

Default: User

Specifies how C-VLAN/S-VLAN tags of packets are processed.

  • User: C-VLAN/S-VLAN tags in user packets are used as user VLAN tags. When a packet leaves a PW, its user VLAN ID will not be changed.
  • Service: C-VLAN/S-VLAN tags in user packets are used as service VLAN tags. When a packet leaves a PW, its service VLAN ID will be changed to the VLAN ID configured for the services.
NOTE:
On the OptiX OSN 580 equipment, Service Tag Role must be set to User.

Source Port

Example:3-EM6F-1(Port-1)(1-2)

Set and query the user-side port or network-side port.

Source VLANs

1-4094

Set one or several VLAN IDs, or not set any VLAN ID.

PRI

0 to 7

Default: null

UNI-NNI E-Line services can be mapped to different PWs based on Port+VLAN+VLAN PRI. If packets need to be forwarded based on Port+VLAN+VLAN PRI, set PRI to an integer ranging from 0 to 7. Value 7 represents the highest priority.

PRI can be set to null, one value, or several values. If PRI is set to several values, separate the values using commas; if PRI is set to an interval, represent the interval in a form like 2-5.

  • If PRI is set to null, packets are mapped to different PWs based on VLAN IDs. In this case, packets whose PRI is set to a value within the range from 0 to 7 can be carried in the E-Line service.
  • If PRI is not set to null, packets are mapped to different PWs based on Port+VLAN+VLAN PRI. In this case, one service VLAN ID must be added for the E-Line service.
Sink Port

Example:3-EM6F-1(Port-1)(1-2)

Set and query the user-side port or network-side port.

The equipment does not support this parameter when Direction is set to UNI-UNI.

Sink VLANs

1-4094

Set one or several VLAN IDs, or not set any VLAN ID.

The equipment does not support this parameter when Direction is set to UNI-UNI.

Bearer Type

PW, QinQ Link

Default value: PW

The Bearer Type (E-Line Service) parameter specifies the bearer type for different types of Ethernet services. The value of this parameter can be set to PW, or QinQ Link.

Value description:
  • PW: The bearer is the PW, and the PW ID needs to be specified.
  • QinQ Link: The bearer is the QinQ link, and the QinQ link ID needs to be specified.
Recommendations:
  • The bearer of the E-Line service V-NNI can be the PW, or QinQ link.
  • The bearer of the E-LAN service V-NNI can be the PW, or QinQ link.

QinQ Link ID

Example: 5

Select and display the QinQ Link ID.

BPDU

Transparently Transmitted, Not Transparently Transmitted

Default value: Not Transparently Transmitted

The BPDU parameter sets whether the service needs transparently transmit the bridge protocol data unit (BPDU) packets. The BPDU is the information transmitted between bridges. It is used to switch information between bridges, and then the spanning tree of the network is computed.

Impact on the System:

If the BPDU transparent transmission identifier of the Ethernet service of an NE is enabled, the port where the service V-UNI resides cannot process the BPDU packets. After the BPDU transparent transmission is enabled, the BPDU packets are transmitted.

Value description:
  • Transparently Transmitted: BPDU packets are transparently transmitted to and processed on the opposite NE instead of being terminated on the local NE.
  • Not Transparently Transmitted: BPDU packets are processed as service packets, which are processed differently according to port attributes. When the port attribute is Tag Aware, BPDU packets are discarded because they do not carry any VLAN IDs.
Recommendations:

If the BPDU packets need be transparently transmitted to the opposite end of the network, set the BPDU to Transparently Transmitted during the service creation.

If the BPDU packets need be processed on the local NE as service packets for computing the network spanning tree, set the BPDU to Not Transparently Transmitted during the service creation.

Association with other parameters:

If the BPDU is set to Transparently Transmitted for the Ethernet services carried by an Ethernet port, the MSTP cannot be enabled. After the MSTP is enabled on the port, the BPDU transparent transmission services cannot be configured on the port.

Deployment Status

Deployed, Undeployed

Displays the current deployment state of a service.
  • Deployed: indicates that the PW configuration data has been applied to an NE.
  • Undeployed: indicates that the PW configuration data has not been applied to an NE.

ARP Dual Feed

Enable, Disable

Specifies whether to enable dual feed. If you set this parameter to Enable for an E-Line service in PW FPS protection, the working and protection PWs both transmit ARP packets.

NOTE:
OptiX OSN 500/550/580 does not support ARP dual-feeding.

PW Dual Receiving

-

PW dual receiving takes effect only for PW FPS (FRR).

NOTE:

OptiX OSN 500 and 550 support PW dual receiving.

OptiX OSN 580 does not support PW dual receiving.

MAC Address Withdrawal upon PW OAM Fault

-

This parameter cannot be set.

NOTE:
OptiX OSN 500/550/580 does not allow a PW OAM fault to trigger MAC address withdrawal.

  • Use preferred: Indicates that the control word is recommended.
Association with other parameters:
  • If Control Word of the PW is Not in use, do not set Control Channel Type of the VCCV to CW; if Control Channel Type of the VCCV is CW, do not modify Control Word of the PW to Not in use.
  • Before changing the parameter value of a PW, you need to ensure that the PW is not bound with the service. After the change, you need to bind the PW with the service, and then check whether the parameter value is changed.
NOTE:

The PW control word must be consistently configured at the two ends of the PW.

Control Channel Type

None, CW, Alert Label

Default value: CW

NOTE:
  • For PWE3 ETH services, Control Channel Type for PCXLG/PCXGA/PCXGB boards with PCBs of Ver.B can be set to CW; the default value for Control Channel Type is Alert Label.
  • For PWE3 ETH services, Control Channel Type for PCXLG/PCXGA/PCXGB boards with PCBs of Ver.A cannot be set to CW; the default value for Control Channel Type is Alert Label.
  • For PWE3 ETH services, Control Channel Type for PCXLX/PCXX boards can be set to CW; the default value for Control Channel Type is Alert Label.

The Control Channel Type parameter specifies the type of channels for transmitting VCCV packets.

VCCV packets are exchanged between PEs to verify connectivity of PWs.

Value description:
  • None: Indicates that the control word is not used to indicate the VCCV control channel information.
  • CW: Indicates that the control word is used to indicate the VCCV control channel information.
  • Alert Label: Indicates VCCV packets in Alert Label encapsulation mode.

Request VLAN

1-4094, Non-specified

Default value: Non-specified

The Request VLAN parameter specifies the ETH request VLAN.

In the case of static PW, the local equipment adds the VLAN tag to the packets when before PW encapsulation. In the case of the dynamic PW, the opposite equipment adds the VLAN tag to the packets before PW encapsulation if the local equipment cannot add the VLAN tag.

Recommendations:

When the Request VLAN parameter is set to Non-specified, the packets are added with 0 VLAN tags.

Association with other parameters:

You need to set the PW Type parameter to Ethernet Tagged Mode.

Before changing the parameter value of a PW, you need to ensure that the PW is not bound with the service. After the change, you need to bind the PW with the service, and then check whether the parameter value is changed.

Maintenance Association

The maintenance association (MA) facilitates the connectivity check (CC) of a network that transports services.

Table 3-345 lists the parameters for an maintenance association.

Table 3-345  Parameters for an maintenance association

Field

Value

Description

Maintenance Domain Name

1-8 characters

Specifies an MD name that is unique in the entire network.

Maintenance Association Name

1-8 characters

Specifies an MA name that is unique in the same MD.

CC Test Transmit Period

3.33ms, 10ms, 100ms, 1s, 10s, 1m, 10m

Default value: 1s

The source end MEP constructs the CC frames, and then transmits them periodically to the destination MEP. After the destination MEP receives the CCM messages from the source end, the CC check function of the source MEP is directly started. Within a certain period (3.5 times of the transmission period), if the destination MEP does not receive the CC packets from the source end, an alarm is automatically reported. The CC Test Transmit Period parameter indicates the transmission period of the unidirectional connectivity check.

Impact on the System:

After the CC check is started, a portion of the bandwidth on the port is used.

Recommendations:

It is recommended that you use three period values, that is, 3.33ms for protection switching, 100ms for performance check, and 1s for connectivity check. The configuration should comply with user requirements. If the fast check is required, set to 3.33ms. Hence, the fault can be detected quickly. The bandwidth used, however, descends with the period value.

MEP Point

A maintenance association end point (MEP) is an edge point in a maintenance association (MA).

Table 3-346 lists parameters for an MEP.

Table 3-346  Parameters for an MEP
