The value of tnMcPeerSyncOperFlags indicates the reason that the synchronization protocol with the multi-chassis peer is down. syncAdminDown(0) Synchronization is administratively down. No recovery needed. peerAdminDown(1) The peering is administratively down. No recovery needed. connectionDown(2) There is a problem with the connection to the multi-chassis peer. The connection will be automatically repaired. No recovery needed internalError(3) There has been an irrecoverable internal error. The synchronization protocol cannot come up again without user intervention. The user must set the tnMcPeerSyncAdminState to 'outOfService', then 'inService'. mcsVersionMismatch(4) There is a mismatch between the versions of the multi-chassis sync protocol running on each peer. platformMismatch(5) There is a mismatch between the platforms of each peer the multi-chassis sync protocol is running on. appVersionMismatch(6) There is a mismatch between the versions of applications attempting to use the multi-chassis sync protocol on the two peers. appSupportMismatch(7) There is a mismatch between the applications supported by the multi-chassis sync protocol on each peer.
