Chapter 2 Alarm Troubleshooting

2.7.27 AUTOSW-LOP (VT-MON)

Clear the AUTOSW-LOP (STSMON) Condition

Step 1 Complete the “Clear the LOP-P Alarm” procedure on page 2-91.

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).

2.7.27 AUTOSW-LOP (VT-MON)

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

SONET Logical Object: VT-MON

The AUTOSW-LOP alarm for the VT monitor (VT-MON) indicates that automatic path protection protection switching occurred because of the “LOP-V” alarm on page 2-92. If the path protection is configured for revertive switching, it reverts to the working path after the fault clears.

Note This condition is only reported if the path protection is set up for revertive switching.

Clear the AUTOSW-LOP (VT-MON) Alarm

Step 1 Complete the “Clear the LOP-V Alarm” procedure on page 2-92.

Step 2 If the alarm 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) in order to report a Service-Affecting (SA) problem.

2.7.28 AUTOSW-PDI

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

SONET Logical Object: STSMON

The Automatic Path Protection Switch Caused by Payload Defect Indication (PDI) condition indicates that automatic path protection switching occurred because of a “PDI-P” alarm on page 2-113. If the path protection is configured for revertive switching, it reverts to the working path after the fault clears.

Note This condition is only reported if the path protection is set up for revertive switching.
