HP Device Manager 4.6 - Configuring DHCP tags

Overview

This white paper demonstrates how to configure DHCP tags.

Configuring a DHCP server for use with PXE

Configuring a DHCP server with the HPDM Server installed on a different machine

If problems occur when using PXE, verify that the DHCP server settings do not conflict with PXE. These issues rarely occur.

The PXE boot ROM uses the DHCP server to get an IP address, as well as other basic networking information such as a

subnet mask or a default gateway.

Note

The network must be configured using DHCP to use the PXE service.

To configure the DHCP server:

1. Make sure that the DHCP server has not been previously configured for a PXE bootstrap.

2. If DHCP options 43 and 60 are set, remove them.

Note

The HPDM PXE service detects the DHCP packets sent by any PXE boot ROMs and offers PXE network parameters without

disturbing the standard DHCP negotiation process. This is called DHCP Proxy.

The DHCP server is now be ready to be used with PXE.

Configuring a DHCP servier with the HPDM Server installed on the same machine

If the HPDM Server is installed with a DHCP server on the same machine, it requires some manual configuration. The HPDM

Server installation process installs the HP PXE service, which provides the PXE remote-imaging function. The service

automatically starts and stops with the operating system. The DHCP server is used by the PXE boot ROM to get an IP

address, as well as other basic networking information such as a subnet mask or a default gateway.

These instructions assume the following:

• The network has already been configured using DHCP.

• The DHCP server has not been previously configured for a PXE bootstrap.

• There are no other TFTP servers running on the same network.

By default, options 60 and 201 are not set in Windows 2000. Add these options to tell PXE clients where to find the HPDM

Server.

To configure the DHCP server:

1. If DHCP option 43 is set, remove it because the HPDM Server is installed on the same machine as the DHCP server.

2. Add option 60, and set the value to PXEClient. If option 60 does not exist, use the following procedure.

A. Select Start > Run.

B. Type Cmd in the box. A Command shell appears.

C. Type netsh, and then press the Enter key.

D. Type dhcp, and then press Enter.

E. Type server \\<server_name> (using the UNC name for the DHCP server).

—or—

Type server <IP_address> (using the IP address of the DHCP server).

A <dhcp server> prompt appears in the command window.

F. Type add optiondef 60 <custom_option_name> STRING 0, and then press Enter.

G. Type set optionvalue 60 STRING “PXEClient“, and then press Enter.

H. To confirm that the settings are correct, type show optionvalue all, and then press Enter.

3. Add option 201 using the following procedure.
