Solution
User initiated, none.
User initiated, none.
Investigate Keepalive failure. Wrap
occurred.
Keepalive failure—SLOS, SLOF, LSF,
or LAIS.
Investigate Keepalive failure. Wrap
occurred.
Keepalive failure—LSD.
WTR period is 10 to 360 seconds (user
configured), node will unwrap at end of
WTR. None.
User initiated, none.
User initiated, none.
Investigate the signal degrade on
neighbor node.
Investigate the signal degrade on
neighbor node.
WTR period is 0 to 1440, or never (user
configured), node will unwrap at end of
WTR. None. Setting WTR to never will
prevent the node from unwrapping.
Investigate why the short path request
was not received.
Check other problems on the short span
as indicated on the neighbor node.
