Service becoming unavailable when the IMA protocol and VPRing protocol are configured at the same time. You need to rectify the faults at the opposite end.
Symptom
If the IMA protocol is configured for symmetrical operation, and if the VPRing protocol is configured for single-ended switching, the services are unavailable in the case of hybrid configuration.
The services become unavailable.
Cause Analysis
The IMA protocol is configured for symmetrical operation, and the VPRing is configured for 1+1 or 1:1 single-ended switching. In this case, if a switching event occurs to the VPRing protocol, and if the IMA protocol detects the failure for the opposite end to receive signals, the local end stops transmitting cells.
