Example of Fetching Dynamic MAC Addresses on a Non-default VLANs
In the following example, TenGigabitEthernet 0/7 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
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
The Dell Networking OS assigns an interface number to each (congured or uncongured) physical and logical interface. Display the
interface index number using the
show interfacecommand from EXEC Privilege mode, as shown in the following example.
The interface index is a binary number with bits that indicate the slot number, port number, interface type, and card type of the
interface. The Dell Networking OS converts this binary index number to decimal, and displays it in the output of the
show
interface
command.
Starting from the least signicant bit (LSB):
• the rst 14 bits represent the card type
• the next 4 bits represent the interface type
• the next 7 bits represent the port number
• the next 5 bits represent the slot number
• the next 1 bit is 0 for a physical interface and 1 for a logical interface
• the next 1 bit is unused
For example, the index 44634369 is 10101010010001000100000001 in binary. The binary interface index for TenGigabitEthernet 0/41
of an Aggregator. Notice that the physical/logical bit and the nal, unused bit are not given. The interface is physical, so this must be
