RPR-IEEE1/1 wrapped on
span EAST (span WEST
Span Neighbor Signal Fail)
Neighbor node wrapped due to
signal fail
Investigate the signal degrade on
neighbor node.
RPR-IEEE1/1 wrapped on
span EAST (span WEST
Span Neighbor Signal
Degrade)
Neighbor node wrapped due to
signal degrade
Investigate the signal degrade on
neighbor node.
RPR-IEEE1/1 wrapped on
span EAST (span WEST
Span Neighbor WTR)
Wrap cleared, node initiated;
Wait to Restore state
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.

Switch)
Neighbor node Forced Switch
initiated by user; Node wrap to
protect failed span; Secondary
problem on the short path
Investigate why the short path request
was not received.
Check other problems on the short span
as indicated on the neighbor node.

span EAST (span WEST
Long Request Manual
Switch)
Neighbor node Manual Switch
initiated by user; Node wrap to
protect failed span; Secondary
problem on the short path
Investigate why the short path request
was not received.
Check other problems on the short span
as indicated on the neighbor node.
RPR-IEEE1/1 wrapped on
span EAST (span WEST
Long Request Signal Fail)
Neighbor node wrapped due to
signal fail
Investigate signal fail on neighbor node.
Investigate why the short path request
was not received.
Check other problems on the short span
as indicated on the neighbor node.
RPR-IEEE1/1 wrapped on
span EAST (span WEST
Long Request Signal
Degrade)
Neighbor node wrapped due to
signal degrade
Investigate signal degrade on neighbor
node. Investigate why short path request
was not received.
Check other problems on the short span
as indicated on the neighbor node.
