# Create a RADIUS scheme named rs1 and enter its view.
<RouterA> system-view
[RouterA] radius scheme rs1
# Specify the primary authentication server and primary accounting server, and configure the
keys for communication with the servers.
[RouterA-radius-rs1] primary authentication 192.168.0.112
[RouterA-radius-rs1] primary accounting 192.168.0.112
[RouterA-radius-rs1] key authentication simple radius
[RouterA-radius-rs1] key accounting simple radius
# Exclude the ISP domain name from the username sent to the RADIUS server.
[RouterA-radius-rs1] user-name-format without-domain
[RouterA-radius-rs1] quit
# Enable RADIUS session control.
[RouterA] radius session-control enable
2.
Configure an authentication domain:
# Create an ISP domain named dm1 and enter its view.
[RouterA] domain dm1
# Configure AAA methods for the ISP domain.
[RouterA-isp-dm1] authentication portal radius-scheme rs1
[RouterA-isp-dm1] authorization portal radius-scheme rs1
[RouterA-isp-dm1] accounting portal radius-scheme rs1
[RouterA-isp-dm1] quit
# Configure domain dm1 as the default ISP domain. If a user enters the username without the
ISP domain name at login, the authentication and accounting methods of the default domain
are used for the user.
[RouterA] domain default enable dm1
3.
Configure portal authentication:
# Configure a portal authentication server.
[RouterA] portal server newpt
[RouterA-portal-server-newpt] ip 192.168.0.111 key simple portal
[RouterA-portal-server-newpt] port 50100
[RouterA-portal-server-newpt] quit
# Configure a portal Web server.
[Router] portal web-server newpt
[RouterA-portal-websvr-newpt] url http://192.168.0.111:8080/portal
[RouterA-portal-websvr-newpt] quit
# Enable cross-subnet portal authentication on GigabitEthernet 1/0/2.
[RouterA] interface gigabitethernet 1/0/2
[RouterA–GigabitEthernet1/0/2] portal enable method layer3
# Reference the portal Web server newpt on GigabitEthernet 1/0/2.
[RouterA–GigabitEthernet1/0/2] portal apply web-server newpt
# Configure the BAS-IP as 20.20.20.1 for portal packets sent from GigabitEthernet 1/0/2 to the
