Table 55. 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 TenGigabitEthernet 1/21, which a member of the
default VLAN, VLAN 1. The SNMP walk returns the values for dot1dTpFdbAddress, dot1dTpFdbPort, and dot1dTpFdbStatus.
Each object comprises 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
TenGigabitEthernet 1/21, the manager returns the integer 118.
Example of Fetching MAC Addresses Learned on the Default VLAN Using SNMP

Example of Fetching MAC Addresses Learned on a Non-default VLAN Using SNMP
In the following example, TenGigabitEthernet 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.

Example of Fetching MAC Addresses Learned on a Port-Channel Using SNMP
Use dot3aCurAggFdbTable to fetch the learned MAC address of a port-channel. The instance number is the decimal conversion of
the MAC address concatenated with the port-channel number.
