Your Ethernet connection
to the managed server must be made using
the Ethernet port that is defined as eth0 on your HMC.
If
you have not installed any additional Ethernet adapters in the PCI
slots
on your HMC, the
primary
integrated Ethernet port is always defined as eth0 or eth1 on
your HMC, if you intend to use the HMC as a DHCP server for your managed
systems.
If you have installed additional Ethernet adapters
in the PCI slots, the
port that is defined as
eth0 depends on the location
and
type of Ethernet adapters you have installed.
Note: These are general
rules
and may not apply for all configurations.
The following
table describes the rules for Ethernet placement by HMC type.
Table 1. HMC types and associated rules for Ethernet placement| HMC type |
Rules for Ethernet placement |

| Rack-mounted HMCs with two integrated
Ethernet ports |
The HMC supports
only one additional Ethernet adapter. - If an additional Ethernet
adapter is installed, that port is defined
as eth0. In this case, the primary integrated Ethernet
port
is then defined as eth1, and the secondary integrated
Ethernet
port is defined as eth2.
- If the Ethernet
adapter is a dual port Ethernet adapter then port labeled
Act/Link A will normally be eth0. The port labeled Act/link
B would be eth1. In this case, the primary
integrated
Ethernet port is then defined as eth2, and the secondary
integrated Ethernet port is defined as eth3.
- If
no adapters are installed, the primary integrated Ethernet port is
defined as eth0.
|
| Stand-alone models with a single integrated
Ethernet port |
The definitions depend
upon the type of Ethernet adapter
you have installed: - If only one Ethernet adapter is installed,
that adapter is defined as eth0.
- 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.
- If no adapters are installed, the integrated Ethernet port
is defined
as eth0.
- If multiple Ethernet adapters have
been installed, see Determining the interface name for an Ethernet adapter.
