Configuring the Priority of BFD Packets

Configuring the Priority of BFD Packets

Context

You can change the priority of BFD packets to implement the following functions:
  • Detect whether packets with different priorities on a link can be forwarded.

  • Ensure that BFD packets with a higher priority are forwarded first.

Procedure

  • To configure priorities for dynamic or static BFD session packets in batches, run the following commands in the BFD view:

    1. Run system-view

      The system view is displayed.

    2. Run bfd

      The BFD view is displayed.

    3. Run tos-exp tos-value { dynamic | static }

      A priority is configured for all the static BFD sessions.

      By default, the priority of BFD packets is 7, representing the highest priority. The value 0 indicates the lowest priority.

    4. Run commit

      The configuration is committed.

  • To configure priorities for a single static BFD session packet, run the following commands in the BFD session view:

    1. Run system-view

      The system view is displayed.

    2. Run bfd session-name

      The BFD session view is displayed.

    3. Run tos-exp tos-value

      A priority is configured for static BFD session packets.

      By default, the priority of BFD packets is 7, representing the highest priority. The value 0 indicates the lowest priority.

    4. Run commit

      The configuration is committed.
