2.6.76 FORCED-REQ-SPAN
The Force Switch Request Span condition applies to optical trunk cards in two-fiber or four-fiber
MS-SPRings when the Force Span command is applied to a MS-SPRing 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.

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
