2.7.133 FORCED-REQ
2.7.133 FORCED-REQ
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
SONET Logical Objects: EQPT, ML1000, ML100T, MLFX, 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.
FORCED-REQ is raised for an IEEE 802.17b-based RPR span if the force was requested in the
Cisco IOS CLI using the “rpr-ieee protection request force-switch {east | west}” command. It clears
from the IEEE 802.17b-based RPR span when you remove the switch in the CLI. For the
IEEE 802.17b-based RPR interface, FORCED-REQ is suppressed by the “RPR-PASSTHR” alarm on
page 2-209. It also suppresses the following alarms:
• MAN-REQ, page 178
• RPR-SF, page 214
• RPR-SD, page 213
• WTR, page 258
Clear the FORCED-REQ Condition
Step 1 If the condition is raised on a SONET entity, complete the “Clear a 1+1 Force or Manual Switch
Command” procedure on page 2-263.
Step 2 If the condition is raised on an IEEE-802.17b-based RPR span, enter the following command in the CLI
in RPR-IEEE interface configuration mode:
router(config-if)#no rpr-ieee protection request force-switch {east | west}
Step 3 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.
2.7.134 FORCED-REQ-RING
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
SONET Logical Object: OCN
The Force Switch Request Ring condition applies to optical trunk cards when the Force Ring command
is applied to BLSRs to move traffic from working to protect. This condition is visible on the network
view Alarms, Conditions, and History tabs and is accompanied by the “WKSWPR” alarm on page 2-258.
The port where the FORCE RING command originated is marked with an “F” on the network view
detailed circuit map.
Clear the FORCED-REQ-RING Condition
Step 1 Complete the “Clear a BLSR External Switching Command” procedure on page 2-269.
