vmVlans3k
Module: CISCO-VLAN-MEMBERSHIP-MIB
OID (symbolic): CISCO-VLAN-MEMBERSHIP-MIB::vmVlans3k
OID (numeric): 1.3.6.1.4.1.9.9.68.1.2.2.1.6
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-write
Description: The VLAN(s) the port is assigned to when the port's vmVlanType is set to multiVlan. This object is not instantiated if not applicable.
The port is always assigned to one or more VLANs and the object may not be set so that there are no vlans assigned.
Each octet within the value of this object specifies a set of eight VLANs, with the first octet specifying VLAN id 2048 through 2055, the second octet specifying VLAN ids 2056 through 2063, etc. Within each octet, the most significant bit represents the lowest numbered VLAN id, and the least significant bit represents the highest numbered VLAN id. Thus, each VLAN of the port is represented by a single bit within the value of this object. If that bit has a value of '1' then that VLAN is included in the set of VLANs; the VLAN is not included if its bit has a value of '0'.
What is vmVlans3k?
This read-write OCTET STRING extends the multiVlan bitmap further to cover VLAN IDs starting at 2048, with the first octet representing VLANs 2048 through 2055. An administrator managing a large VLAN deployment uses it to assign a multiVlan port into VLANs in the 2048+ range that the lower-numbered bitmaps can't reach. For example, setting the appropriate bit would add VLAN 2060 to the port's set of assigned VLANs.
