nnMstBrgAddress

Module: NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB

OID (symbolic): NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB::nnMstBrgAddress

OID (numeric): 1.3.6.1.4.1.45.5.5.1.1.3

Node type: OBJECT-TYPE

Type: MacAddress

Access: read-only

Description: The MAC address used by this bridge when it must be referred to in a unique fashion. It is recommended that this be the numerically smallest MAC address of all ports that belong to this bridge. However it is only required to be unique. When concatenated with nnMstCistBridgePriority or nnMstBridgePriority a unique BridgeIdentifier is formed which is used in the Spanning Tree Protocol.

What is nnMstBrgAddress?

Reports the MAC address that uniquely identifies this bridge; combined with the bridge priority (nnMstCistBridgePriority or nnMstBridgePriority) it forms the full Bridge Identifier used throughout the Spanning Tree Protocol.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.45.5.5.1.1.3
snmpwalk -v2c -c public <target> NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB::nnMstBrgAddress

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.45.5.5.1.1.3.1
snmpget -v2c -c public <target> NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB::nnMstBrgAddress.1
