Configuring cross-subnet portal authentication with extended
functions
Network requirements
As shown in
:
•
Switch A is configured for cross-subnet extended portal authentication. If the host fails security check
after passing identity authentication, the host can access only subnet 192.168.0.0/24. After
passing security check, the host can access Internet resources.
•
The host accesses Switch A through Switch B.
•
A RADIUS server serves as the authentication/accounting server.
