member of the default VLAN, VLAN 1. The SNMP walk returns the values for dot1dTpFdbAddress,
dot1dTpFdbPort, and dot1dTpFdbStatus.
Each object is comprised 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.
