ARP Ping has the following operational issues:•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 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 is assigned using the LC command.

•Upon successfully assigning an IP address using ARP Ping, DHCP is automatically disabled.

Select one of the following 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 and log in to it.3.Run the ARP Ping commands from the server.Table 3-4lists the ARP Ping commands.Table 3-4 ARP Ping Commands

ARP Command

Description

 

 

arp -s

Assigns the 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.

 

 

ping

Tests network connections and verifies that the iLO 2 MP LAN port is configured with the

 

appropriate IP address.

 

 

 

 

NOTE: 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 a label on the server.

IMPORTANT: Make sure you obtain the MAC address to the iLO 2 MP LAN and not the MAC address to 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 command prompt (C: >) , enter arp -sto assign the IP address to the iLO MAC address.

The syntax is as follows:

arp -s<IP address you want to assign to the iLO MAC address> <iLO 2 MAC address> Example from Windows

arp -s 192.0.2.1 00-00-0c-07-ac-00

6.At the DOS command prompt, enter ping followed by the IP address to verify that the iLO 2 MP LAN port is configured with the appropriate IP address. The destination address is the IP address that is mapped to the iLO MAC address. Perform this task from the PC that has the ARP table entry.

The syntax is as follows:

ping <IP address just assigned to the iLO MAC address> Example from Windows
