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>
