nnMstBridgeVlanMap
Module: NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB
OID (symbolic): NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB::nnMstBridgeVlanMap
OID (numeric): 1.3.6.1.4.1.45.5.5.1.6.1.2
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-write
Description: This gives the bitwise representation for the Vlans Mapped for a particular instance. 512*8 bits used to represent 4096 vlans. The 0th bit represents vlan 1, 1st bit represents vlan 2 and so forth. If vlan n is mapped to a particular instance then the n-1 indexed bit is set
What is nnMstBridgeVlanMap?
Reports (and on some platforms allows setting) which of the 4096 possible VLANs are mapped to this spanning-tree instance, encoded as a 512-octet bitmap where bit n-1 set means VLAN n belongs to the instance.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.45.5.5.1.6.1.2 snmpwalk -v2c -c public <target> NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB::nnMstBridgeVlanMap
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.45.5.5.1.6.1.2.1 snmpget -v2c -c public <target> NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB::nnMstBridgeVlanMap.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.45.5.5.1.6.1.2.1 s <value>
