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 unusedFor example, the index 72925242 is 100010110001100000000111010 in binary.
