Configuring Association Between CFM and BFD

Configuring Association Between CFM and BFD

Context

For details about principles and usage scenarios of association between CFM and BFD, see CFM Association.

Association between CFM and BFD is bidirectional. When CFM detects a link fault, it will notify BFD of the fault. When BFD detects a link fault, it will notify CFM of the fault.

Perform the following operations on the device of a link configured with CFM at one side and BFD at the other side.

Pre-configuration Tasks

Before configuring association between CFM and BFD, complete the following tasks:

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run oam-mgr

    The OAM management view is displayed.

  3. Run the following commands as required.

    Table 7-24 Association between CFM and BFD
    Scenario Configuration 1 Configuration 2

    Faults need to be transmitted bidirectionally between CFM and BFD.

    Run the oam-bind cfm md md-name ma ma-name bfd-session bfd-session-id command to configure BFD and CFM to report faults to each other.

    NOTE:

    If the oam-bind cfm md md-name ma ma-name bfd-session bfd-session-id command is run, oam-bind ingress bfd -session bfd-session-id egress cfm md md-name ma ma-name and oam-bind ingress cfm md md-name ma ma-name egress bfd-session bfd-session-id will be displayed in the configuration file.

    Use the following commands:
    • Run the oam-bind ingress bfd -session bfd-session-id egress cfm md md-name ma ma-name command to configure BFD to report faults to CFM.

    • Run the oam-bind ingress cfm md md-name ma ma-name egress bfd-session bfd-session-id command to configure CFM to report faults to BFD.

    Faults need to be transmitted unidirectionally between CFM and BFD.

    Run either of the following commands based on the transmission direction:
    • Run the oam-bind ingress bfd -session bfd-session-id egress cfm md md-name ma ma-name command to configure BFD to report faults to CFM.

    • Run the oam-bind ingress cfm md md-name ma ma-name egress bfd-session bfd-session-id command to configure CFM to report faults to BFD.

    None

  4. Run commit

    The configuration is committed.
