Configuration prerequisites and guidelines
• Configure IP addresses for the switch and servers as shown in Figure 54 and make sure the
host, switch, and servers can reach each other.
• Configure the RADIUS server properly to provide authentication and accounting functions.
• Make sure the IP address of the portal device added on the portal authentication server is the IP
address (20.20.20.1) of the switch's interface connecting the host. The IP address group
associated with the portal device is the subnet of the host (8.8.8.0/24).
Configuration procedure
Perform the following tasks 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
# 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
# Exclude the ISP domain name from the username sent to the RADIUS server.
[SwitchA-radius-rs1] user-name-format without-domain
[SwitchA-radius-rs1] quit
# Enable RADIUS session control.
[SwitchA] radius session-control enable
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
