2.7.349 RPR-PROT-CONFIG-MISM
The IEEE 802.17b-based RPR Protection is Active condition, raised by the ML card, indicates that ring
protection is active and that steering protection as defined in IEEE 802.17b is active.
IEEE 802.17b-based RPR provides hitless protection switching for all protected traffic on a ring. Its
steering protection mechanism ensures that each station receives span change information (such as fail
or restoration) in time to make protection switching decisions within the 50-millisecond time frame.
The condition clears when steering protection is no longer active.For more information about steering,
refer to the Cisco ONS 15454 and Cisco ONS 15454 SDH Ethernet Card Software Feature and
Configuration Guide.
This condition is suppressed by the
Clear the RPR-PROT-ACTIVE Condition
Locate and clear any service-affecting SONET error that might have caused a protection switch, in turn
Step 1
triggering the RPR-PROT-ACTIVE condition. Clearing the SONET condition will clear
RPR-PROT-ACTIVE.
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.
2.7.349 RPR-PROT-CONFIG-MISM
The IEEE 802.17b-based RPR Protection Configuration Mismatched alarm is raised by an ML card
when it detects that its steering protection scheme is mismatched with other vendors' equipment
configured for wrapping protection. The ONS 15454 does not support IEEE 802.17b's optional
wrapping scheme.
The alarm clears when the other vendor's equipment configuration is changed to utilize steering
protection.
RPR-PROT-CONFIG-MISM is suppressed by the
Clear the RPR-PROT-CONFIG-MISM Alarm
You cannot clear this alarm from the ONS 15454; rather, it is caused by incompatible vendor equipment
Step 1
configuration. See that equipment's support information to correct the configuration for steering instead
of wrapping. This, in turn, will cause RPR-PROT-CONFIG-MISM to clear.
If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport
Step 2
for more information or call Cisco TAC (1 800 553-2447) to report a Service-Affecting (SA) problem.
