2.7.340 RING-MISMATCH
Default Severity: Major (MJ), Service-Affecting (SA)
SONET Logical Object: OCN
A Procedural Error Mismatch Ring alarm occurs when the ring name of the ONS 15454 node that is
reporting the alarm does not match the ring name of another node in the BLSR. Nodes connected in a
BLSR must have identical ring names to function. This alarm can occur during BLSR provisioning.
RING-MISMATCH is somewhat similar to RING-ID-MIS, but it applies to BLSR protection discovery
instead of DWDM node discovery.
Note For more information about DWDM cards, refer to the Cisco ONS 15454 DWDM Reference Manual.
