Determining the interface name for an Ethernet adapter

If you configure the HMC as a DHCP server, that server can operate only on the network interface card (NIC) connectors that the HMC identifies as eth0 and eth1. You might also need to determine which NIC connector you need to plug the Ethernet cable into. Learn more about determining which NIC connectors the HMC identifies as eth0 and eth1.

To determine the name the HMC has assigned to an Ethernet adapter, do the following:
  1. Open the restricted shell terminal. Select HMC Management > Open Restricted Shell Terminal.
  2. Type the following at the command line: tail -f /var/log/messages. The messages log scrolls when new events occur.
  3. Plug in your Ethernet cable. If the cable was already plugged in, then unplug it, wait 5 seconds, and plug in the cable again. The restricted shell scrolls to display a message when you plug-in the cable. The following example entry shows that this Ethernet port is identified as eth0: Aug 28 12:41:20 termite kernel: e1000: eth0: e1000_watchdog: NIC Link is Up 100.
  4. Repeat this procedure for all other Ethernet ports, and record your results.
  5. Type Ctrl+C to stop the tail command.
