Console Connection and Setup Configuring the iLO MP LAN Using ARP Ping Step 4. Open a browser, telnet, or SSH client and enter the default host name. The default host name is the letters mp followed by the 12 characters of the MAC address. The iLO MP Log In window opens. Configuring the iLO 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: • 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 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 (factory-set default); but ARP Ping does not start for three minutes after the iLO MP is booted. This applies to every subsequent boot of the iLO MP until an IP address is obtained by DHCP or has been assigned by using the LC command or ARP Ping succeeds. There are two methods to use the ARP Ping utility: 1. 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. 2. Locate an existing server on the network, log into it, and run the ARP Ping commands from the server. Table 6-4 lists the ARP Ping commands.

Configuring the iLO 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:
•
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 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 (factory-set default); but ARP Ping
does not start for three minutes after the iLO MP is booted. This applies to every subsequent boot of the
iLO MP until an IP address is obtained by DHCP or has been assigned by using the
LC
command or ARP
Ping succeeds.
There are two methods to use the ARP Ping utility:
1. 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.
2. Locate an existing server on the network, log into it, and run the ARP Ping commands from the server.
Table 6-4 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:
Step 1.
Obtain the iLO MP MAC address. To set the IP address using ARP, you must know the MAC
address of the iLO MP LAN. You can find the MAC address of the iLO MP LAN on a label on the
server.

ARP Ping Commands
ARP Command
Description
arp -s
This command assign the IP address to the iLO MP MAC address. This ARP table
entry maps the MAC address of the iLO MP LAN interface to the static IP address
designated for that interface.
ping
This command tests network connections. It verifies the iLO MP LAN port is
configured with the appropriate IP address.
