Configuring cross-subnet portal authentication

Network requirements
As shown in
Switch A is configured for cross-subnet portal authentication. Before passing portal authentication,
•
the host can access only the portal server. After passing portal authentication, it can access Internet
resources.
The host accesses Switch A through Switch B.
•
A RADIUS server serves as the authentication/accounting server.
