Chapter 2 Alarm Troubleshooting

Alarm Procedures

When the alarm is raised on an OC-3 or OC-12 port, it is sometimes an indication that the OC-3 or OC-12

port expects a specific line rate and the input line rate source does not match the input line rate of the

optical receiver.

Clear the LOF (OCN) Alarm

Step 1 Complete the “Clear the LOF (EC1) Alarm” procedure on page 2-95.

Step 2 If the alarm does not clear, or if you need assistance conducting network troubleshooting tests, call

Cisco TAC to report a Service-Affecting (SA) problem (1-800-553-2447).

2.7.140 LOF (STSTRM)

Default Severity: Critical (CR), Service-Affecting (SA)

SONET Logical Object: STSTRM

A Loss of Frame alarm for an STS circuit termination indicates that the LOF has occurred at the

terminating point of the circuit (such as an OC-N port). It is similar to the “LOF (OCN)” alarm on

page 2-95.

Clear the LOF (STSTRM) Alarm

Step 1 Complete the “Clear the LOF (OCN) Alarm” procedure on page 2-96.

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.

2.7.141 LOGBUFR90

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

SONET Logical Object: SYSTEM

The Log Buffer Over 90 alarm indicates that the per-NE queue of incoming alarm, event, or update

capacity of 5000 entries is over 90 percent full. LOGBUFR90 will clear if CTC recovers. If it does not

clear, LOGBUFROVFL occurs.

Note LOGBUFR90 is an informational alarm and does not require troubleshooting.

2.7.142 LOGBUFROVFL

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

SONET Logical Object: SYSTEM
