MCS Database
multi chassis synchronization database
A database that contains the dynamic state information created on any of the NEs by any application using its services. The individual entries in the MCS Database are always paired by peering-relation, sync-tag and application-id. At any time, the specific entry is related to the single redundant-pair objects (such as two saps on two different NEs), and hence stored in a local MCS Database of the respective NEs.
