dot1dBasePortCircuit

Module: BRIDGE-MIB

OID (symbolic): BRIDGE-MIB::dot1dBasePortCircuit

OID (numeric): 1.3.6.1.2.1.17.1.4.1.3

Node type: OBJECT-TYPE

Type: OBJECT IDENTIFIER

Access: read-only

Description: Circuit OID.

What is dot1dBasePortCircuit?

Provides a unique object instance identifier for a bridge port when multiple ports share the same interface index value, such as when several virtual circuits map to one physical interface. It disambiguates ports that would otherwise appear identical by their interface index alone.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.17.1.4.1.3
snmpwalk -v2c -c public <target> BRIDGE-MIB::dot1dBasePortCircuit

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.17.1.4.1.3.1
snmpget -v2c -c public <target> BRIDGE-MIB::dot1dBasePortCircuit.1
