Monitoring and Maintaining SSO-BFD
Monitoring and Maintaining SSO-BFD
The BFD packets are dropped if there is a problem on the link and the BFD signals its client. A
corresponding action occurs to bring down the feature. However, during a switchover, if the peer router
goes down, the router undergoing the switchover detects the failure when the CEF path comes up.
To monitor and maintain the SSO-BFD feature, enter any of the following commands in privileged
EXEC mode:
Command
Router# show enhanced-timers
Router# show bfd neighbour detail
Router# debug bfd ha
Router# debug bfd event
Router# debug bfd packet
Configuration Examples of SSO-BFD
This section explains the following configuration examples:
•

•
The following BFD timers are supported for the SSO-BFD feature:

Purpose
Displays status of the values set on the timers.
This command is used on the standby PRE.
Displays complete details of the BFD neighbor
including the routing protocol registered with it.
This command is used on the active PRE.
Displays logs specific to the BFD HA process.
The command can also be used to check whether
there is a failure in transmission of BFD packets
during a switchover causing the peer router to
detect a failure. This command can be enabled on
the standby PRE also.
Checks for packets received or lost from the
router undergoing a switchover.
Checks whether the router undergoing a
switchover failed to transmit BFD packets.
