Chapter 2 Alarm Troubleshooting

Alarm Procedures

Clear the FEPRLF Alarm

Step 1 To troubleshoot the FE alarm, determine which node and port link directly to the port reporting the FE

alarm.

Step 2 Log into the node that links directly to the port reporting the FE condition.

Step 3 Clear the main alarm. Refer to the appropriate alarm section in this chapter for instructions.

Step 4 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).

2.7.91 FORCED-REQ

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

SONET Logical Objects: STSMON, VT-MON

The Force Switch Request on Facility or Port condition occurs when you enter the Force command on a

port to force traffic from a working port to a protect port or protection span (or from a protect port to a

working port or span). You do not need to clear the condition if you want the Force switch to remain.

Clear the FORCED-REQ Condition

Step 1 Complete the “Clear a 1+1 Force or Manual Switch Command” procedure on page 2-158.

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).

2.7.92 FORCED-REQ-SPAN

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

SONET Logical Object: OCN

The Force Switch Request Span condition applies to optical trunk cards in spans when the Force Span

command is applied to a span to force traffic from working to protect or from protect to working. This

condition appears on the network view Alarms, Conditions, and History tabs. The port where the Force

Span command was applied is marked with an “F” on the network view detailed circuit map.

This condition can also be raised in 1+1 facility protection groups. If traffic is present on a working port

and you use the Force command to prevent it from switching to the protect port (indicated by “FORCED

TO WORKING”), FORCED-REQ-SPAN indicates this force switch. In this case, the force is affecting

not only the facility, but the span.

Clear the FORCED-REQ-SPAN Condition

Step 1 Complete the “Clear an External Switching Command on a Path Protection Span” procedure on

page 2-161.
