Deriving Interface Indices

The Dell Networking OS assigns an interface index to each (configured and unconfigured) physical and logical
interface, and displays it in the output of the show interface command.
The interface index is a binary number with bits that indicate the slot number, port number, interface type,
and card type of the interface. 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 significant bit (LSB):
the first 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 72925242 is 100010110001100000000111010 in binary. The binary interface index for
TeGigabitEthernet 1/21 of a 48-port 10/100/1000Base-T line card with RJ-45 interface. Notice that the
physical/logical bit and the final, unused bit are not given. The interface is physical, so represent this type of
interface by a 0 bit, and the unused bit is always 0. These 2 bits are not given because they are the most
significant bits, and leading zeros are often omitted.
NOTE:
The interface index does not change if the interface reloads or fails over. If the unit is renumbered
(for any reason) the interface index changes during a reload.
To display the interface number, use the following command.
Display the interface index number.
