Configuring The Ilo 2 Mp Lan Using Arp Ping; Arp Ping Commands - HP Integrity BL870c Operation Manual

1. Obtain the factory-set DNS name from the iLO Network Information Tag on the server. The
DNS name is 14 characters long. It consists of the letters MP followed by the 12 characters
of the MAC address. For example:
mp0014c29c064f
This address is assigned to the iLO 2 MP system board. The system board has a unique MAC
address that identifies the hardware on the network.
2. Connect the MP LAN cable from the server to an active network port.
3. Apply ac power to the server.
4. Open a browser, Telnet, or SSH client and enter the fully-qualified DNS name (the full path
name ending in the DNS name). The iLO 2 Log In window appears.
5. Log in using the default user name and password (Admin/Admin).
CAUTION:
can access iLO 2 until you change the default user name and password.
HP strongly recommends you assign user groups and rights before proceeding.

Configuring the iLO 2 MP LAN Using ARP Ping

This method can only be used for entry class.
NOTE:
You can use ARP Ping regardless of the status of DHCP unless an IP address has ever
been acquired using DHCP. Once an IP address is assigned using DHCP, ARP Ping is permanently
disabled. Some DHCP server options can cause the apparent issuance of ARP Ping to iLO 2,
which negates the DHCP over DNS method.
The Address Resolution Protocol (ARP) and Packet Internet Grouper (Ping) utility uses ARP
packets to ping (discover) a device on the local network segment. The IP address you assign to
the server must use the same network segment (subnet) as the system assigning the address.
ARP does not work across routed or switched networks.
Use the ARP Ping utility to assign a static IP address when you do not have access to the console
serial port (RS-232) or when DHCP is not available.
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 iLO 2 is booted. This applies to every
subsequent boot of iLO 2 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 3-4 lists the ARP Ping commands.

When DHCP is enabled, the system is vulnerable to security risks because anyone
