Configuring OAM Mapping

Configuring OAM Mapping

OAM mapping accelerates AC fault detection and notification.

Usage Scenario

On an MPLS L2VPN, PEs and CEs do not notify the others of their master/backup status and link status. To detect the PW and AC status, deploy OAM separately for PWs and ACs to detect the PW and AC status. Then enable OAM mapping on the PEs to associate PW OAM and AC OAM. This configuration accelerates AC fault detection and notification.

Pre-configuration Tasks

Before configuring OAM mapping, complete the following tasks:

  • Configure network layer parameters for devices on the MPLS L2VPN to communicate.
  • Configure PWs.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The AC interface view is displayed.

    NOTE:

    The AC interface must be an Ethernet sub-interface.

  3. Run mpls l2vpn oam-mapping 1ag md md-name ma ma-name

    OAM mapping is enabled to associate PW OAM with AC OAM.

    • Before running this command, configure Ethernet OAM for ACs.

    • In the display mpls l2vc oam-mapping [ interface interface-type interface-number ] command output, Local AC OAM State displays the AC status if the mpls l2vpn oam-mapping command has been run, and Local AC OAM State is always Up and irrelevant to the AC status if the mpls l2vpn oam-mapping has not been run.

  4. Run commit

    The configuration is committed.

Checking the Configurations

After configuring OAM mapping, check the configurations.
  • Run the display mpls l2vc oam-mapping [ interface interface-type interface-number ] command to check OAM mapping information.

# Run the display mpls l2vc oam-mapping [ interface interface-type interface-number ] command. The command output shows that AC OAM State is Up.
