ieee8021QBridgeTpFdbPort

Module: IEEE8021-Q-BRIDGE-MIB

OID (symbolic): IEEE8021-Q-BRIDGE-MIB::ieee8021QBridgeTpFdbPort

OID (numeric): 1.3.111.2.802.1.1.4.1.2.2.1.2

Node type: OBJECT-TYPE

Type: IEEE8021BridgePortNumberOrZero

Access: read-only

Description: Either the value '0', or the port number of the port on which a frame having a source address equal to the value of the corresponding instance of ieee8021QBridgeTpFdbAddress has been seen. A value of '0' indicates that the port number has not been learned but that the device does have some forwarding/filtering information about this address (e.g., in the ieee8021QBridgeStaticUnicastTable). Implementors are encouraged to assign the port value to this object whenever it is learned, even for addresses for which the corresponding value of ieee8021QBridgeTpFdbStatus is not learned(3).

What is ieee8021QBridgeTpFdbPort?

The port number on which a frame from this MAC address was seen (or 0 if the port hasn't been learned but filtering info still exists), the key field for tracing which switch port a given MAC address is behind.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.4.1.2.2.1.2
snmpwalk -v2c -c public <target> IEEE8021-Q-BRIDGE-MIB::ieee8021QBridgeTpFdbPort

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.4.1.2.2.1.2.1
snmpget -v2c -c public <target> IEEE8021-Q-BRIDGE-MIB::ieee8021QBridgeTpFdbPort.1
