description
is a string of 1 to 51 characters.
The default description of a BFD session is Null.
You can run the
undo description
command to delete the description of a BFD session.
NOTE
To modify a parameter after a BFD session has been created, run a corresponding command (such as
process-interface-status
,
min-tx-interval
,
min-rx-interval
,
detect-multiplier
,
tos-exp
,
wtr
, or
description
). The modification takes effect immediately without the
commit
command configured.

3.7.5 Checking the Configuration
By viewing the adjusted BFD parameters, you can check whether the configurations are
successful.
Prerequisite
The configurations for BFD parameter adjustment are complete.
Context
NOTE
Before viewing BFD session information, you must set session parameters and create the session.
Procedure

Example
After the configuration is complete, run the
display bfd session
all
verbose
command to see
that
Min Tx Interval
is 1000 milliseconds,
Min Rx Interval
is 1000 milliseconds,
WTR
Interval
is 60000 milliseconds, and
Session Description
is
RouterA_to_RouterB
.
