Port Interface Index

To determine the interface index (IfIndex), you can calculate it, or use the CLI command provided in this section.

As a result of channelization support, the ifIndex of each channelization–capable port increases by 4. The number is reserved for the 3 sub-ports when channelization is enabled.

VSP 4450 Series and XA1400 Series

For switches that do not include channelization-capable ports, use the following equation to determine the IfIndex of a port:

(192 x slot number) + (port number – 1)

For example, the interface index of port 1/50 is 241.

The VSP 4450 Series and XA1400 Series use one slot.

VSP 4900 Series, VSP 7200 Series, VSP 7400 Series, VSP 8200 Series, and VSP 8400 Series

For switches that include channelization-capable ports, use the following equations to determine the IfIndex of a port:

The slot numbers are 1-2 for the VSP 4900 Series.

The slot numbers are 1-2 for the VSP 7200 Series.

The slot number is 1 for the VSP 7400 Series.

The slot numbers are 1-2 for the VSP 8200 Series.

The slot numbers are 1-4 for VSP 8400 Series.

CLI command

To determine the port interface index through the CLI, use the following command:

show interfaces gigabitEthernet

The following example shows an output for this command:

Switch:1(config)#show interfaces gigabitEthernet
