[CAUSE] The notification tmnxMcPeerRingsOperStateChanged is sent when the operational state, with respect to multi-chassis ring operation, of a peer changed. unknown | No rings are configured for this peer. inService | The signaling connection for mc-ring operation | is operational. outOfService | The signaling connection for mc-ring operation | has timed out. transition | Not implemented. [EFFECT] unknown | None. inService | The signaling connection for mc-ring operation | is operational. outOfService | None, as long as no rings are in state 'broken'.The MCS connection is likely to be out of service. If some rings are in state 'broken', those rings will suffer degraded functionality. transition | Not implemented. [RECOVERY] The recovery depends on the operational state of the ring: unknown | None. inService | None. outOfService | Restore the IP connectivity between the local peer and the remote peer. transition | Not implemented.
