Chapter 2 Alarm Troubleshooting

Alarm Procedures

Note SSM-ST3E is an informational condition. It does not require troubleshooting.

2.6.170 SSM-ST4

Not Alarmed (NA), Non-Service Affecting (NSA)

The SSM Stratum 4 (ST4) Traceable condition occurs when the synchronization message quality level is lowered to ST4. The message quality is not used because it is below ST3.

Note SSM-ST4 is an informational condition. It does not require troubleshooting.

2.6.171 SSM-STU

Not Alarmed (NA), Non-Service Affecting (NSA)

The SSM Synchronization Traceability Unknown (STU) condition occurs when the reporting node is timed to a reference that does not support SSM, but the ONS 15327 has SSM support enabled. STU can also occur if the timing source is sending out SSM messages but SSM is not enabled on the ONS 15327.

Procedure: Clear the STU Condition

Step 1 In node view, click the Provisioning > Timing tabs.

Step 2 If Sync Messaging is checked, deselect the box.

Step 3 If Sync Messaging is unchecked, check the box.

Step 4 Click Apply.

Step 5 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).

2.6.172 SSM-TNC

Not Alarmed (NA), Non-Service Affecting (NSA)

The SSM Transit Node Clock (TNC) Traceable condition occurs when the synchronization message quality level is changed to TNC.

Note SSM-TNC is an informational condition. It does not require troubleshooting.

2.6.173 SWMTXMOD

Critical (CR), Service Affecting (SA)
