Configuring extended cross-subnet portal authentication
Network requirements
As shown in Figure 60, Switch A supports portal authentication. The host accesses Switch A through
Switch B. A portal server acts as both a portal authentication server and a portal Web server. A
RADIUS server acts as the authentication/accounting server.
Configure Switch A for extended cross-subnet portal authentication. Before passing portal
authentication, the host can access only the portal server. After passing portal identity authentication,
the host accepts security check. If the host fails the security check it can access only the subnet
192.168.0.0/24. After passing the security check, the host can access other network resources.

Configuration prerequisites and guidelines
• Configure IP addresses for the switch and servers as shown in Figure 60 and make sure the
host, switch, and servers can reach each other.
• Configure the RADIUS server correctly to provide authentication and accounting functions.
• Make sure the IP address of the portal device added on the portal 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.
