stpxSMSTInstanceVlansMapped3k4k

Module: CISCO-STP-EXTENSIONS-MIB

OID (symbolic): CISCO-STP-EXTENSIONS-MIB::stpxSMSTInstanceVlansMapped3k4k

OID (numeric): 1.3.6.1.4.1.9.9.82.1.14.5.1.3

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 2048 through 4095. The first octet corresponds to VLANs with VlanIndex values of 2048 through 2055; the second octet to VLANs 2056 through 2063; 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 stpxSMSTInstanceVlansMapped3k4k?

A read-only bitmap, one bit per VLAN, indicating which VLANs (in the range 2048-4095) are mapped to a given MST instance.
