a3ComSysBridgeBackbonePort

Module: A3COM-SWITCHING-SYSTEMS-BRIDGE-MIB

OID (symbolic): A3COM-SWITCHING-SYSTEMS-BRIDGE-MIB::a3ComSysBridgeBackbonePort

OID (numeric): 1.3.6.1.4.1.43.29.4.10.2.1.8

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The number of the port selected as the backbone segment port when the corresponding value of a3ComSysBridgeMode is is expressMode(1). The value of this object can range from 1 to the corresponding value of a3ComSysBridgePortCount, however, some bridges may support only a subset of ports as backbone ports. If the corresponding value of a3ComSysBridgeMode is not expressMode(1), the value of this object is ignored.

What is a3ComSysBridgeBackbonePort?

Identifies which physical port acts as the high-speed backbone when in express mode (port number 1-N). Engineers assign this to the fastest upstream link to ensure core traffic uses optimal paths. Port 1 might be a gigabit uplink, making it the backbone; others become access ports.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.43.29.4.10.2.1.8
snmpwalk -v2c -c public <target> A3COM-SWITCHING-SYSTEMS-BRIDGE-MIB::a3ComSysBridgeBackbonePort

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.43.29.4.10.2.1.8.1
snmpget -v2c -c public <target> A3COM-SWITCHING-SYSTEMS-BRIDGE-MIB::a3ComSysBridgeBackbonePort.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.43.29.4.10.2.1.8.1 i <value>
