Configuring cross-subnet portal authentication
Network requirements
As shown in Figure 404, configure Switch A to perform cross-subnet portal authentication for users.
Before passing portal authentication, the host can access only the portal server. After passing portal
authentication, the host can access Internet resources. Use the IMC server as the RADIUS server for user
authentication, authorization, and accounting.
