(Optional) Configuring Fast Fault Notification

(Optional) Configuring Fast Fault Notification

OAM mapping and physical-layer fault notification can accelerate AC fault detection and notification.

Context

Fast fault notification is classified into the following types:
NOTE:

When a PW encounters a fault, OAM mapping does not trigger AC interfaces to go Down. If PEs and CEs support Ethernet OAM, using OAM mapping is recommended.

Procedure

  • Configure OAM mapping.
    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.

      • Ethernet OAM for ACs must be configured before the mpls l2vpn oam-mapping 1ag md md-name ma ma-name command is run.

      • After running the mpls l2vpn oam-mapping command, run the display mpls l2vpn oam-mapping [ interface interface-type interface-number ] command to check VC status. In the command output, Local AC OAM State indicates the AC link status.

    4. Run commit

      The configuration is committed.

  • Configure physical layer fault notification.
    1. Run system-view

      The system view is displayed.

    2. Run interface interface-type interface-number

      The AC interface view is displayed.

      • The AC interface must be an Ethernet main interface.

      • This interface must have a VC configured.

    3. Run mpls l2vpn trigger if-down

      Physical layer fault notification is enabled.

    4. Run commit

      The configuration is committed.
