dot1qTpFdbPort
Module: Q-BRIDGE-MIB
OID (symbolic): Q-BRIDGE-MIB::dot1qTpFdbPort
OID (numeric): 1.3.6.1.2.1.17.7.1.2.2.1.2
Node type: OBJECT-TYPE
Type: Integer32
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 dot1qTpFdbAddress 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 dot1qStaticUnicastTable). Implementors are encouraged to assign the port value to this object whenever it is learned, even for addresses for which the corresponding value of dot1qTpFdbStatus is not learned(3).
What is dot1qTpFdbPort?
This holds the port number where a specific MAC address was last seen, or 0 if the address is known through static configuration only. Engineers use this to locate where a device is physically connected by searching for its MAC address. A value of 5 means that MAC address was seen entering on port 5.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.17.7.1.2.2.1.2 snmpwalk -v2c -c public <target> Q-BRIDGE-MIB::dot1qTpFdbPort
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.17.7.1.2.2.1.2.1 snmpget -v2c -c public <target> Q-BRIDGE-MIB::dot1qTpFdbPort.1
