HP-UX AAA Server A.08.00.01 Administrator's Guide

25 Using DHCP
The HP-UX AAA server can act as a Dynamic Host Configuration Protocol (DHCP)
relay to request IP address assignments from a DCHP server. Currently, only DHCPv4
is supported. To use DHCP, you must associate address pools with the AAA server’s
incoming requests. The following are the two methods you can use to associate address
pools with incoming requests:
• Associate an address pool with specific users or specific realms
• Configure HP-UX AAA Server decision files to associate an address pool for a
condition. See Chapter 27 (page 405) for more information.
The HP-UX AAA Server can act as a relay for most DHCP servers.
Required DHCP Server Features
DHCP server has the ability to assign addresses from its IP address pools based on the
User Class or Vendor Class Identification attribute.
Recommended DHCP Server Features
• DHCP server has the ability to assign IP addresses outside the network it resides
in. Many RADIUS/DHCP deployments will require this capability.
• DHCP server has the ability to send to ports above the well-known port range
(0-1023). Without this capability the AAA server will not be able to run as a non-root
process.
Defining DHCP Address Pools for Specific Users
Use the following steps to associate DHCP address pools with specific users. The
procedure for associating address pools with specific users depends on where the user
profile is stored.
NOTE: The name of the pool referenced in the user profile must match the name of
a pool defined on the DHCP server.
To Associate an Address Pool with a User Profile in AAA Server Flat Files
1. On the navigation tree, select Local Realms.
The Local Realms screen is displayed.
2. Click the Users icon for the realm the user is in.
The Users screen appears.
3. Click the Edit icon next to the user you want to associate with an address pool.
The Add/Modify Users screen appears.
