This object contains the 4096 bit vector indicating which VIDs are assigned to this MSTID. The high order bit of the first octet corresponds to the first bit of the vector, while the low order bit of the last octet corresponds to the last bit of this portion of the vector. A bit that is on (equal to 1) indicates that the corresponding VID is assigned to this MSTID. One VID cannot be shared by multiple instances. If the configured VID is assigned to other instance, the VID is removed from the other instance and assigned to the requested instance. If the VID is not assigned to any MSTI, the VID will be assigned to to CIST automatically. But the VID is not assigned to any MSTI and CIST by removing from provMstpBridgeCistVlanList, the VID is not assigned automatically. The manager must care of such situation, and must assign the VID manually.
