2.7.353 RPR-SPAN-MISMATCH
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) to report a
Service-Affecting (SA) problem.
2.7.353 RPR-SPAN-MISMATCH
Default Severity: Major (MJ), Service-Affecting (SA)
SONET Logical Objects: ML100T, ML1000, MLFX
The IEEE 802.17b-based RPR-SPAN-MISMATCH alarm is caused by span misprovisioning, span
forced switching, physical miscabling, or a circuit loopback.
Miscabling problems between this node’s east or west span and its neighboring span in the same
direction can also cause this alarm, as will provisioning an XC loopback on a circuit that carries
RPR-IEEE traffic.
If a traffic-affecting issue such as the “AIS-P” alarm on page 2-37, the “GFP-LFD” alarm on page 2-119,
the “LOP-P” alarm on page 2-155, the “RFI-P” alarm on page 2-205, or the “UNEQ-P” alarm on
page 2-252 occurs, it in turn suppresses RPR-SPAN-MISMATCH.
Note Clearing a circuit XC loopback does not always cause the loopback to clear. If this is the case, a FORCE
switch is used to clear the RPR-SPAN-MISMATCH alarm. The FORCE might cause a traffic hit.
RPR- SPAN-MISMATCH is suppressed by “RPR-PASSTHR” alarm on page 2-209.
Clear the RPR-SPAN-MISMATCH Alarm
Step 1 Locate and clear any primary cause provisioning errors.
Step 2 If the alarm does not clear, locate and correct any span cabling errors.
Step 3 If the alarm does not clear, look for and clear XC loopbacks on the spans.
Step 4 If the alarm does not clear, configure a FORCE switch on the 802.17b-based RPR span and then clear
the switch. To do this, enter the following CLI command in RPR-IEEE interface provisioning mode:
router(config)# rpr-ieee protection request forced-switch {east | west}
Clear the switch by entering the following command:
router(config)# no rpr-ieee protection request forced-switch {east | west}
Step 5 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) to report a Service-Affecting (SA) problem.
