Table 51. MIB Objects for Fetching Dynamic MAC Entries in the Forwarding Database
MIB Object
dot1dTpFdbTable
dot1qTpFdbTable
dot3aCurAggFdb Table
In the following example, R1 has one dynamic MAC address, learned off of port GigabitEthernet 1/21,
which a member of the default VLAN, VLAN 1. The SNMP walk returns the values for dot1dTpFdbAddress,
dot1dTpFdbPort, and dot1dTpFdbStatus.
Each object is comprised of an OID concatenated with an instance number. In the case of these objects,
the instance number is the decimal equivalent of the MAC address; derive the instance number by
converting each hex pair to its decimal equivalent. For example, the decimal equivalent of E8 is 232, and
so the instance number for MAC address 00:01:e8:06:95:ac is.0.1.232.6.149.172.
The value of dot1dTpFdbPort is the port number of the port off which the system learns the MAC address.
In this case, of GigabitEthernet 1/21, the manager returns the integer 118.

In the following example, GigabitEthernet 1/21 is moved to VLAN 1000, a non-default VLAN. To fetch the
MAC addresses learned on non-default VLANs, use the object dot1qTpFdbTable. The instance number is
the VLAN number concatenated with the decimal conversion of the MAC address.
