Configuring Layer 3 Portal Authentication with Extended Functions

Network requirements
Switch A is configured for Layer 3 extended portal authentication. When users have passed identity
authentication but have not passed security authentication, they can access only subnet
192.168.0.0/24. After passing security authentication, they can access unrestricted Internet
resources.
The host accesses Switch A through Switch B.
A RADIUS server serves as the authentication/accounting server.
