Usage Guidelines

Usage Scenario

In practice, multiple BFD sessions need to be configured. To differentiate BFD sessions, run the description command to configure a description for a BFD session. A meaningful description is recommended.

Configuration Impact

It is difficult to identify a BFD session that is not configured or whose description is deleted.

Precautions

If you run the description command in the same BFD session view multiple times, only the latest configuration takes effect.

The description command takes effect only for statically configured BFD sessions but does not take effect for dynamic BFD sessions or BFD sessions with automatically negotiated discriminators.

Example

# Set the description of the BFD session named atoc.

<HUAWEI> system-view
[HUAWEI] bfd atoc
[HUAWEI-bfd-session-atoc] description SwitchA_to_SwitchC
