stpxSMSTInstanceVlansMapped1k2k

Module: CISCO-STP-EXTENSIONS-MIB

OID (symbolic): CISCO-STP-EXTENSIONS-MIB::stpxSMSTInstanceVlansMapped1k2k

OID (numeric): 1.3.6.1.4.1.9.9.82.1.14.5.1.2

Node type: OBJECT-TYPE

Type: OCTET STRING

Access: read-only

Description: A string of octets containing one bit per VLAN for VLANS with VlanIndex values of 0 through 2047. The first octet corresponds to VLANs with VlanIndex values of 0 through 7; the second octet to VLANs 8 through 15; etc. The most significant bit of each octet corresponds to the lowest value VlanIndex in that octet.

For each VLAN, if it is mapped to this MST instance, then the bit corresponding to that VLAN is set to '1'. If the length of this string is less than 256 octets, any 'missing' octets are assumed to contain the value of zero.

What is stpxSMSTInstanceVlansMapped1k2k?

A read-only bitmap, one bit per VLAN, indicating which VLANs (in the range 0-2047) are mapped to a given MST instance.
