Configuring the iLO 2 MP LAN Using ARP Ping

The Address Resolution Protocol (ARP) and Packet Internet Grouper (Ping) utility uses ARP
packets to ping, or discover, a device on the local network segment. The IP address you assign
to the server must use the same network segment, or subnet, as the computer assigning the
address. ARP does not work across routed or switched networks.
ARP Ping operational issues include the following:
• You can use ARP Ping regardless of the status of DHCP, unless an IP address has ever been
acquired using DHCP
• When ARP Ping is successful, DHCP status is disabled
• Some DHCP server options can cause the apparent issuance of ARP Ping to the iLO 2 MP
which will negate the DHCP/DDNS method
• The PC and the server must be on the same physical subnet
• When a new server is first booted, DHCP is automatically available (the factory-set default),
but ARP Ping does not start until three minutes after the iLO 2 MP is booted. This applies
to every subsequent boot of the iLO 2 MP until an IP address is obtained by DHCP or has
been assigned using the LC command, or ARP Ping succeeds
There are two ways to use the ARP Ping utility:
• Connect a PC to the network that is on the same physical subnet as the server and run the
ARP Ping commands from the PC.
• Locate an existing server on the network, log into it, and run the ARP Ping commands from
the server.
Table 3-8 lists the ARP Ping commands.

The following procedure explains how to use the ARP Ping utility using a PC that is connected
to the network that is on the same physical subnet as the server.
To configure a static IP address using the ARP Ping utility, follow these steps:
1. Obtain the iLO 2 MP MAC address. To set the IP address using ARP, you must know the
MAC address of the iLO 2 MP LAN. You can find the MAC address of the iLO 2 MP LAN
on the label located on the server front panel.
IMPORTANT:
MAC address of the server core LAN.
2. Verify that an active LAN cable on the local subnet is connected to the iLO 2 MP LAN port
on the server.
3. Access a PC on the same physical subnet as the server.
4. Open a DOS window on the PC.
5. At the DOS prompt, enter arp -s to assign the IP address to the iLO MAC address.
arp -s<IP address you assign to the iLO MAC address> <iLO MAC address>
For example:
arp -s 192.0.2.1 00-00-0c-07-ac-00
72 Installing the Server
Description
This command assigns an IP address to the iLO 2 MP MAC address. This ARP table entry
maps the MAC address of the iLO 2 MP LAN interface to the static IP address designated for
that interface.
This command tests network connections. It verifies that the iLO 2 MP LAN port is configured
with the appropriate IP address.
Make sure you obtain the MAC address of the iLO 2 MP LAN and not the
