Make sure the IP address of the portal device added on the portal server is the IP address of the
•
interface connecting users (20.20.20.1 in this example), and the IP address group associated with
the portal device is the network segment where the users reside (8.8.8.0/24 in this example).
Perform the following configuration to configure cross-subnet portal authentication on Switch A:
1.
Configure a RADIUS scheme:
# Create a RADIUS scheme named rs1 and enter its view.
<SwitchA> system-view
[SwitchA] radius scheme rs1
# Set the server type for the RADIUS scheme. When using the IMC server, set it to extended.
[SwitchA-radius-rs1] server-type extended
# Specify the primary authentication server and primary accounting server, and configure the keys
for communication with the servers.
[SwitchA-radius-rs1] primary authentication 192.168.0.112
[SwitchA-radius-rs1] primary accounting 192.168.0.112
[SwitchA-radius-rs1] key authentication simple radius
[SwitchA-radius-rs1] key accounting simple radius
# Specify that the ISP domain name should not be included in the username sent to the RADIUS
server.
[SwitchA-radius-rs1] user-name-format without-domain
[SwitchA-radius-rs1] quit
2.
Configure an authentication domain:
# Create an ISP domain named dm1 and enter its view.
[SwitchA] domain dm1
# Configure AAA methods for the ISP domain.
[SwitchA-isp-dm1] authentication portal radius-scheme rs1
[SwitchA-isp-dm1] authorization portal radius-scheme rs1
[SwitchA-isp-dm1] accounting portal radius-scheme rs1
[SwitchA-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.
[SwitchA] domain default enable dm1
3.
Configure portal authentication:
# Configure the portal server as follows:
Name: newpt
IP address: 192.168.0.1 1 1
Key: portal, in plain text
Port number: 50100
URL: http://192.168.0.1 1 1:8080/portal.
[SwitchA] portal server newpt ip 192.168.0.111 key simple portal port 50100 url
http://192.168.0.111:8080/portal
# Enable portal authentication on the interface connecting Switch B.
[SwitchA] interface vlan-interface 4
[SwitchA–Vlan-interface4] portal server newpt method layer3
[SwitchA–Vlan-interface4] quit
