(Optional) Configuring Session Descriptions

By configuring session descriptions when you create static BFD sessions, you can better understand the configurations. Generally, a description explains the devices on both ends of a session.

Context

The description command is valid only for statically configured BFD sessions, but invalid for the dynamically configured BFD sessions and the auto-negotiated BFD sessions with static discriminators.

Procedure

Access the system view.
```
system-view
```
Access the BFD session view.
```
bfd cfg-name
```
Set a BFD session description.
```
description description
```
By default, the BFD session description is empty.
Commit the configuration.
```
commit
```
To change session parameters (by using the min-tx-interval, min-rx-interval, detect-multiplier, tos-exp, wtr, or description command) after a BFD session is created, you must run the commit command. In this case, the configurations can take effect.
