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.
