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. Fetching Dynamic MAC
Addresses on the Default VLAN
In Figure 44-22, TenGigabitEthernet 1/21 is moved to VLAN 1000, a non-default VLAN. Use the objects
dot1qTpFdbTable to fetch the MAC addresses learned on non-default VLANs. The instance number is the
VLAN number concatenated with the decimal conversion of the MAC address.
Figure 44-22. Fetching Dynamic MAC Addresses on Non-default VLANs
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.

Deriving Interface Indices
FTOS assigns an interface number to each (configured or unconfigured) physical and logical interface.
Display the interface index number using the command
show interface from EXEC Privilege mode, as
shown in Figure 44-24.
