Request Forced Switch)
User initiated forced
switch on span WEST on
node
User initiated, none.
RPR-IEEE1/1 protected on
span EAST (span WEST User
Request Manual Switch)
User initiated manual
switch on span WEST on
node
User initiated, none.
RPR-IEEE1/1 protected on

Detect Signal Fail)
SONET Layer 1 signal fail
detected
Investigate Keepalive failure. Wrap
occurred.
Keepalive failure—SLOS, SLOF, LSF, or
LAIS.
RPR-IEEE1/1 protected on
span EAST (span WEST
Span Neighbor Signal
Degrade)
SONET Layer 1 signal fail
detected
Investigate Keepalive failure. Wrap
occurred.
Keepalive failure—LSD.
RPR-IEEE1/1 protected on
span EAST (span WEST Self
Detect Wait to Restore
[WTR])
Wrap cleared, node
initiated; Wait to Restore
(WTR) state
WTR period is 10 to 360 seconds (user
configured), node will unwrap at end of
WTR. None.
RPR-IEEE1/1 protected on
span EAST (span WEST
Span Neighbor Forced
Switch)
Neighbor node Forced
Switch initiated by user.
Node wrap to protect
failed span
User initiated, none.
RPR-IEEE1/1 protected on
span EAST (span WEST
Span Neighbor Manual
Switch)
Neighbor node Manual
Switch initiated by user.
Node wrap
User initiated, none.
RPR-IEEE1/1 protected on
span EAST (span WEST
Span Neighbor Signal Fail)
Neighbor node protected
due to signal fail
Investigate the signal degrade on neighbor
node.
RPR-IEEE1/1 protected on
span EAST (span WEST
Span Neighbor Signal
Degrade)
Neighbor node protected
due to signal degrade
Investigate the signal degrade on neighbor
node.
RPR-IEEE1/1 protected 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.
RPR-IEEE1/1 protected on
span EAST (span WEST
Long Request Forced 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.
