Identify A NIC Port¶

If you ever need to, you can have a specific port of a physical NIC on the router blink to visually identify it.

To do that, run the following command:

vrouter> cmd identify-port pci-b131s0f1 duration 300

Where pci-b131s0 is the network-port you want to identify.

The command can be interrupted before the specified duration (in seconds) by hitting ctrl-c.

Note

If you see the following error message:

Cannot identify NIC: Operation not supported

It means that your network adapter does not support LED control.

Tip

To display the list of all network-ports and their description, you may use the following command:

vrouter> show state / network-port
