• The host accesses Switch A through Switch B.

• A RADIUS server serves as the authentication/accounting server.

Configuration procedure

When configuring cross-subnet portal authentication, follow these guidelines:

• Configure IP addresses for the host, switches, and servers as shown in Figure 52 and

make sure they

can reach each other.

• Configure the RADIUS server properly to provide authentication and accounting functions for users.

• 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
