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.

Setting the media speed:

Learn how to specify the media speed which includes the speed and duplex mode of the Ethernet
adapter.
1. In the navigation area, click HMC Management.
2. Click Change network settings.
3. Click the LAN Adapters tab.
4. Select the LAN adapter you want to work with and click Details.
5. In the Local area network information section, select Autodetection or the appropriate media speed
and duplex combination.
6. Click OK.

Selecting a private or open network:

A private service network consists of the HMC and the managed systems. A private service network is
restricted to consoles and the systems they manage, and is separate from your company network. An

Rules for Ethernet placement
The definitions depend upon the type of Ethernet
adapter you have installed:
v If only one Ethernet adapter is installed, that adapter
is defined as eth0.
v If the Ethernet adapter is a dual port Ethernet adapter,
then the port labeled Act/link A will be eth0. The port
labeled Act/link B would be eth1. In this case, the
primary integrated Ethernet port is then defined as
eth2.
v If no adapters are installed, the integrated Ethernet
port is defined as eth0.
v If multiple Ethernet adapters have been installed, see
"Determining the interface name for an Ethernet
adapter."
