Table 16-1. MIB Objects for Fetching Dynamic MAC Entries in the Forwarding Database<br />
MIB Object OID Description MIB<br />
dot1dTpFdbTable .1.3.6.1.2.1.17.4.3 List the learned unicast MAC addresses on the<br />
default VLAN.<br />

1.1.5<br />
In Figure 16-8, R1 has one dynamic MAC address, learned off of port TenGigabitEthernet 1/21, which is a<br />
member of the default VLAN, VLAN 1. The SNMP walk returns the values for dot1dTpFdbAddress,<br />
dot1dTpFdbPort, and dot1dTpFdbStatus.<br />
Each object is comprised an OID concatenated with an instance number. In the case of these objects, the<br />
instance number is the decimal equivalent of the MAC address; derive the instance number by converting<br />
each hex pair to its decimal equivalent. For example, the decimal equivalent of E8 is 232, and so the<br />
instance number for MAC address 00:01:e8:06:95:ac is .0.1.232.6.149.172.<br />
The value of dot1dTpFdbPort is the port number of the port off which the system learns the MAC address.<br />
In this case, of TenGigabitEthernet 1/21, the manager returns the integer 118.<br />
Figure 16-8. Fetching Dynamic MAC Addresses on the Default VLAN<br />
In Figure 16-9, TenGigabitEthernet 1/21 is moved to VLAN 1000, a non-default VLAN. Use the objects<br />
dot1qTpFdbTable to fetch the MAC addresses learned on non-default VLANs. The instance number is the<br />
VLAN number concatenated with the decimal conversion of the MAC address.<br />
