Chapter 2 Alarm Troubleshooting
Alarm Procedures
2.7.233 SSM-STU
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
SONET Logical Objects: BITS, DS1, NE-SREF, OCN
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 15310-CL or ONS 15310-MA has SSM
support enabled. SSM-STU can also occur if the timing source is sending out SSM messages but SSM
is not enabled on the system.
Clear the SSM-STU Condition
Step 1 In node view, click the Provisioning > Timing > BITS Facilities tabs.
Step 2 If the Sync. Messaging Enabled check box for the BITS source is checked, uncheck the box.
Step 3 If the Sync. Messaging Enabled check box for the BITS source is not checked, check the box.
Step 4 Click Apply.
Step 5 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).
2.7.234 SSM-TNC
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
SONET Logical Objects: BITS, NE-SREF, OCN
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.
2.7.235 SW-MISMATCH
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
SONET Logical Object: EQPT
The Software Mismatch condition occurs during software upgrade when there is a mismatch between
software versions. The card connecting to the CTX-2500 card is running an older version than the
CTX-2500 card is.
Clear the SW-MISMATCH Condition
Step 1 Log into a node on the network. If you are already logged in, continue with Step 2.
Step 2 In node view, position the cursor over the optical or electrical traffic card slot reporting the alarm.
Step 3 Right-click the card. Choose Reset Card from the shortcut menu.
