Deriving Interface Indices
The Dell Networking OS assigns an interface index to each (configured and unconfigured) physical or
logical interface, and displays it in the output of the show interface command.
Dell#show interface fortyGigE 0/4
fortyGigE 0/4 is down, line protocol is down
Description: if_0/4 | if_forty
Hardware is DellForce10Eth, address is 74:86:7a:ff:6f:08
Current address is 74:86:7a:ff:6f:08
Pluggable media not present
Interface index is 51528196
[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. The system converts this binary index number to decimal, and
displays it in the
show command output.
Starting from the least significant bit (LSB) in the preceding figure:
• The first 14 bits represent the card type of a physical interface or the interface number of a logical
interface.
• The next 4 bits represent the interface type.
• The next 12 bits represent the slot and port numbers.
• The next bit is 0 for a physical interface and 1 for a logical interface.
• The last next is unused.
The Slot-Port Number value is derived from the slotId and portId parameters as follows: slotPortNum =
((slotId +1) * IFM_IFINDEX_MAX_PORTS_PER_SLOT + portId).
On the Z9500, the IFM_IFINDEX_MAX_PORTS_PER_SLOT value is 192 (10G). For backward compatibility,
the IFM_IFINDEX_MAX_PORTS_PER_SLOT value is 128 on other Dell Networking switches.
The slotId value is derived as follows: slotId = (slotPortNum / IFM_IFINDEX_MAX_PORTS_PER_SLOT) -1.
The portId value is derived as follows: portId = slotPortNum % IFM_IFINDEX_MAX_PORTS_PER_SLOT.
