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.
2.7.135 FORCED-REQ-SPAN
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
SONET Logical Object: EC1, OCN
DWDM Logical Objects: 2R, ESCON, FC, GE, ISC, TRUNK
The Force Switch Request Span condition can apply to optical trunk cards in two-fiber or four-fiber
BLSRs when the Force Span command is applied to a BLSR 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.
FORCED-REQ can 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 a BLSR External Switching Command” procedure on page 2-269.
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.

Step 2 If the condition does not clear, log into the Technical Support Website at
