usrBRBaseBridgeAddress

Module: Usr-bridge-MIB

OID (symbolic): Usr-bridge-MIB::usrBRBaseBridgeAddress

OID (numeric): 1.3.6.1.4.1.429.4.14.1.1

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 usrBRStpPriority a unique BridgeIdentifier is formed which is used in the Spanning Tree Protocol.

What is usrBRBaseBridgeAddress?

This is the bridge's own MAC address, used to refer to it uniquely and, when concatenated with usrBRStpPriority, forms the 8-byte Bridge Identifier used in the Spanning Tree Protocol; it is recommended to be the numerically smallest MAC address of the bridge's own ports.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.429.4.14.1.1
snmpwalk -v2c -c public <target> Usr-bridge-MIB::usrBRBaseBridgeAddress

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.429.4.14.1.1.1
snmpget -v2c -c public <target> Usr-bridge-MIB::usrBRBaseBridgeAddress.1
