Application name	bfd
Event name	bfdDownEvent
Default severity	warning
Message format string	BFD: Network-instance network-instance - Session from local-address:local-discriminator to remote-address:remote-discriminator has transitioned to the down-state state with local-diagnostic code: local-diagnostic-str ( local-diagnostic-code) and remote-diagnostic code: remote-diagnostic-str ( remote-diagnostic-code)
Cause	This notification is generated when a BFD session transitions to the Down or Admin Down state from an Up state.
Effect	The specified BFD session is now down. If the new state is Down, the session may be down due to a failure see the local or remote diagnostic code. If the new state is Admin-Down the session is down due to administrative reasons.
