usrBRTpFdbPort
Module: Usr-bridge-MIB
OID (symbolic): Usr-bridge-MIB::usrBRTpFdbPort
OID (numeric): 1.3.6.1.4.1.429.4.14.3.1.1.2
Node type: OBJECT-TYPE
Type: INTEGER
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 usrBRTpFdbAddress has been seen. A value of '0' indicates that the port number has not been learned but that the bridge does have some forwarding/filtering information about this address (e.g. in the usrBRStaticTable). Implementors are encouraged to assign the port value to this object whenever it is learned even for addresses for which the corresponding value of usrBRTpFdbStatus is not learned(3).
What is usrBRTpFdbPort?
This reports either '0' (meaning the port hasn't been learned but the bridge still has forwarding/filtering information about the address, e.g. via a static entry) or the actual port number on which a frame with this MAC as source address was last seen, letting an admin trace which physical port a given end-station is connected through.
