mSTInstanceVlansMapped
Module: PRVT-MST-MIB
OID (symbolic): PRVT-MST-MIB::mSTInstanceVlansMapped
OID (numeric): 1.3.6.1.4.1.738.1.5.107.1.1.2.5.1.2
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: A string of octets containing one bit per VLAN. The first octet corresponds to VLANs with VlanIndex values of 0 through 7; the second octet to VLANs 8 through 15; etc. The least 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'.
What is mSTInstanceVlansMapped?
This read-only bitmap reports which VLANs (index 0-7 in the first octet's low bit upward) are currently mapped to this MST instance; a set bit means that VLAN's spanning tree topology is governed by this instance.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.738.1.5.107.1.1.2.5.1.2 snmpwalk -v2c -c public <target> PRVT-MST-MIB::mSTInstanceVlansMapped
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.738.1.5.107.1.1.2.5.1.2.1 snmpget -v2c -c public <target> PRVT-MST-MIB::mSTInstanceVlansMapped.1
