•
Make sure the IP address of the portal device added on the portal server is the public IP address of
the interface connecting users (20.20.20.1 in this example), the private IP address range for 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), and the public IP address range for the IP address group is
the public network segment 20.20.20.0/24.
•
Configure IP addresses for the switch and servers as shown in
and make sure that the host,
switch, and servers can reach each other.
•
Configure the RADIUS server properly to provide authentication and accounting functions for users.
Perform the following configuration to configure re-DHCP authentication on the switch:
1.
Configure a RADIUS scheme:
# Create a RADIUS scheme named
rs1
and enter its view.
<Switch> system-view
[Switch] radius scheme rs1
# Set the server type for the RADIUS scheme. When using the IMC server, set the server type to
extended
.
[Switch-radius-rs1] server-type extended
# Specify the primary authentication server and primary accounting server, and configure the keys
for communication with the servers.
[Switch-radius-rs1] primary authentication 192.168.0.113
[Switch-radius-rs1] primary accounting 192.168.0.113
[Switch-radius-rs1] key authentication simple radius
[Switch-radius-rs1] key accounting simple radius
# Specify that the ISP domain name should not be included in the username sent to the RADIUS
server.
[Switch-radius-rs1] user-name-format without-domain
[Switch-radius-rs1] quit
2.
Configure an authentication domain:
# Create an ISP domain named
dm1
and enter its view.
[Switch] domain dm1
# Configure AAA methods for the ISP domain.
[Switch-isp-dm1] authentication portal radius-scheme rs1
[Switch-isp-dm1] authorization portal radius-scheme rs1
[Switch-isp-dm1] accounting portal radius-scheme rs1
[Switch-isp-dm1] quit
# Configure domain
dm1
as the default ISP domain for all users. Then, if a user enters the
username without the ISP domain at logon, the authentication and accounting methods of the
default domain are used for the user.
[Switch] domain default enable dm1
3.
Configure portal authentication:
# Configure the portal server as follows:
{
Name:
newpt
{
IP address:
192.168.0.111
{
Key:
portal
in plain text
