This table defines the association of VIDs into VLANs. There is an entry in this table, for each component of the bridge, for each VID that is: a) a VID belonging to a VLAN associated with more than one VID; and b) not the Primary VLAN of that VID. The entry in this table contains the Primary VID of the VLAN. By default, this table is empty, meaning that every VID is the Primary VID of a single-VID VLAN. VLANs that are associated with only one VID SHOULD NOT have an entry in this table. The writable objects in this table need to be persistent upon reboot or restart of a device. **NOTE: this object is deprecated due to re-indexing of the table.
