2.7.250 WKSWPR
2.7.250 WKSWPR
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
SONET Logical Objects: EQPT, OCN, STSMON, VT-MON
The Working Switched To Protection condition occurs when a line experiences the “LOS (OCN)” alarm
on page 2-98.
This condition is also raised when you use the FORCE SPAN 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 2-99.
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).
2.7.251 WTR
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
SONET Logical Objects: EQPT, OCN, STSMON, VT-MON
The Wait To Restore condition occurs when the “WKSWPR” condition on page 2-146 is raised and 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.
Note WTR is an informational condition. It does not require troubleshooting.
2.8 DS-1 Line Alarms
The 15310-CL-CTX, DS1-28/DS3-EC1-3, and DS1-84/DS3-EC1-3 card DS1 ports provide three line
types: ESF, D4, or Unframed. The choice of framing format determines the line alarms that the card
reports. Table 2-13 lists the line alarms reported under each format. The choice of framing format does
not affect the reporting of STS alarms.
