rxr1dTpFdbPort

Module: IBM-RXR-MIB

OID (symbolic): IBM-RXR-MIB::rxr1dTpFdbPort

OID (numeric): 1.3.6.1.4.1.2.6.26.1.4.3.1.2

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 rxr1dTpFdbAddress 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 rxr1dStaticTable). Implementors are encouraged to assign the port value to this object whenever it is learned even for addresses for which the corresponding value of rxr1dTpFdbStatus is not learned(3).

What is rxr1dTpFdbPort?

Reports which port a frame from this MAC address was last seen on — 0 means the port hasn't been learned even though the bridge has some static forwarding rule for the address, e.g. via rxr1dStaticTable. An admin uses this to trace which port a given device is physically connected behind.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2.6.26.1.4.3.1.2
snmpwalk -v2c -c public <target> IBM-RXR-MIB::rxr1dTpFdbPort

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.2.6.26.1.4.3.1.2.1
snmpget -v2c -c public <target> IBM-RXR-MIB::rxr1dTpFdbPort.1
