Chapter 2 Alarm Troubleshooting

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 2-146is 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 2-13lists the line alarms reported under each format. The choice of framing format does not affect the reporting of STS alarms.
