vmVlans2k
Module: CISCO-VLAN-MEMBERSHIP-MIB
OID (symbolic): CISCO-VLAN-MEMBERSHIP-MIB::vmVlans2k
OID (numeric): 1.3.6.1.4.1.9.9.68.1.2.2.1.5
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 1024 through 1031, the second octet specifying VLAN ids 1032 through 1039, 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 vmVlans2k?
This read-write OCTET STRING extends the multiVlan bitmap to cover the VLAN ID range starting at 1024, with the first octet representing VLANs 1024 through 1031. An administrator on a switch supporting an extended VLAN range uses this object to assign or verify a port's membership in higher-numbered VLANs beyond the first 1024. For example, setting a bit in the third octet's range would add VLAN 1040 to that multiVlan port's membership.
