Chapter 2 Alarm Troubleshooting
2.7.441 WKSWPR
This condition is raised as NA severity by default. However, it indicates that traffic is squelched due to
node failure, that is, traffic outage. Traffic outage can be caused by different problems, such as multiple
instances of the “LOS (OCN)” alarm on page 2-164, the “AIS-L” condition on page 2-37, or node power
outage. VT-SQUELCH-L is symptomatic and indicates that the user must investigate which node in a
ring is being isolated and what causes node isolation.
Note VT-SQUELCH-L is an informational condition.
2.7.441 WKSWPR
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
SONET Logical Objects: EQPT, OCN, STSMON, VT-MON
DWDM Logical Objects: 2R, ESCON, FC, GE, ISC
The Working Switched To Protection condition occurs when a line experiences the “LOS (OCN)” alarm
on page 2-164, the “SD (DS1, DS3)” condition on page 2-217, or the “SD (TRUNK)” condition on
page 2-220.
This condition is also raised when you use the Manual Switch, APS Switch, FORCE SPAN, FORCE
RING or MANUAL SPAN command at the network level. WKSWPR is visible on the network view
Alarms, Conditions, and History tabs.
Clear the WKSWPR Condition
Step 1 Complete the “Clear the LOS (OCN) Alarm” procedure on page 2-165.
Step 2 If the condition does not clear, log into the Technical Support Website at
http://www.cisco.com/techsupport for more information or call Cisco TAC 1 800 553-2447.
2.7.442 WORK-QUEUE-FULL
Default Severity: Not Alarmed (NA)
Logical Object: EQPT
The Work Queue Full condition occurs when the netTask Queue in VxWorks has filled up and task
operations for the card is postponed.
2.7.443 WTR
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
SONET Logical Objects: EC1, EQPT, ML1000, ML100T, MLFX, OCN, STSMON, VT-MON
DWDM Logical Objects: 2R, ESCON, FC, GE, ISC, TRUNK
The Wait To Restore condition for SONET and DWDM objects occurs when the “WKSWPR” condition
on page 2-258 is raised, but the wait-to-restore time has not expired, meaning that the active protect path
cannot revert to the working path. The condition clears when the timer expires and traffic switches back
to the working path.
