Loading...How to retrieve BFD adjacency information on a Cisco Catalyst 9500 Switch?
To retrieve BFD adjacency information on a Cisco Switch, first enable privileged EXEC mode. Then, use the command 'show bfd neighbors [details]'.
What to do if there is a lack of debugging information about BFD packets on a Cisco Switch?
If you lack debugging information about BFD packets on a Cisco Switch, use the command 'debug bfd [packet | event]'.
