Deriving Interface Indices - Dell PowerEdge M IO Aggregator Command Reference Manual

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
shown in Figure
Figure 16-11. Display the Interface Index Number
FTOS#show interface tengig 1/21
TenGigabitEthernet 1/21 is up, line protocol is up
Hardware is Dell Force10Eth, address is 00:01:e8:0d:b7:4e
Current address is 00:01:e8:0d:b7:4e
Interface index is 72925242
[output omitted]
The interface index is a binary number with bits that indicate the slot number, port number, interface type,
and card type of the interface. FTOS converts this binary index number to decimal, and displays it in the
output of the
