Configuring Association Between a BFD Session and an Interface to Trigger the Associated Interface in Down State

Configuring Association Between a BFD Session and an Interface to Trigger the Associated Interface in Down State

Pre-configuration Tasks

Before configuring association between a BFD session and an interface, create a BFD session.


Only the S5720EI, S5720HI, S5730HI, S6720EI, S6720HI, and S6720S-EI support this function.


  1. Run system-view

    The system view is displayed.

  2. Run oam-mgr

    The OAM management view is displayed.

  3. Run oam-bind ingress bfd-session bfd-session-id trigger if-down egress interface interface-type interface-number

    A BFD session is configured to report faults to an interface.

    By default, a BFD session is not enabled to report faults to an interface.

    When a BFD session detects a fault, the physical status of the interface bound to the BFD session becomes Down.


    The physical interface associated with BFD cannot be the interface of the BFD link. Otherwise, a link deadlock occurs.
