HP A6600 Configuration Manual page 157

For re-DHCP authentication, the router must be configured as a DHCP relay agent (instead of a DHCP
server), and the portal-enabled interface must be configured with a primary IP address (a public IP
address) and a secondary IP address (a private IP address). For information about DHCP relay agent
configuration, see Layer 3—IP Services Configuration Guide.
Make sure that the IP address of the portal device added on the portal server is the private IP address of
the interface connecting users (10.0.0.1, in this example) and that the IP address group associated with
the portal device is the private network segment where the users reside (10.0.0.0/24, in this example).
Configure IP addresses for the router and servers as shown in
router, and servers can reach each other.
Perform configurations on the RADIUS server to ensure that the user authentication and accounting
functions can work normally.
Configuration procedure
Configure the router:
Configure a RADIUS scheme.
1.
# Create a RADIUS scheme named rs1, and enter its view.
<Router> system-view
[Router] radius scheme rs1
# Set the server type for the RADIUS scheme. When using the iMC server, you must set the server type to
extended.
[Router-radius-rs1] server-type extended
# Specify the primary authentication server and primary accounting server, and configure the keys for
communication with the servers.
[Router-radius-rs1] primary authentication 192.168.0.113
[Router-radius-rs1] primary accounting 192.168.0.113
[Router-radius-rs1] key authentication radius
[Router-radius-rs1] key accounting radius
# Specify that the ISP domain name should not be included in the username sent to the RADIUS server.
[Router-radius-rs1] user-name-format without-domain
[Router-radius-rs1] quit
Configure an authentication domain.
2.
# Create an ISP domain named dm1 and enter its view.
[Router] domain dm1
# Configure AAA methods for the ISP domain.
[Router-isp-dm1] authentication portal radius-scheme rs1
[Router-isp-dm1] authorization portal radius-scheme rs1
[Router-isp-dm1] accounting portal radius-scheme rs1
[Router-isp-dm1] quit
# Configure dm1 as the default ISP domain for all users. Then, if a user enters a username without any
ISP domain at logon, the authentication and accounting methods of the default domain are used for the
user.
[Router] domain default enable dm1
Configure portal authentication.
3.
# Configure the portal server as needed:
