PPPoE Users of a Campus Network Access the Internet

PPPoE Users of a Campus Network Access the Internet

As shown in Figure 7-7, a large number of users on a campus network access the Internet through a switch. In order to ensure network security, network access of users needs to be controlled. Only authenticated users are allowed to access network resources authorized by the administrator.

Figure 7-7  Device functioning as a PPPoE server

The device functions as a PPPoE server, and the hosts on the campus network connect to the Internet through PPPoE. Each host is an independent client that obtains a unique account. After a PPoE client sends a PPPoE authentication request, the PPPoE server forwards the user name and password of the client to the authentication server. If the authentication is successful, the server allows the client to access the network. If the authentication fails, the server forbids the client to access the network.

PPPoE authentication requires that each host should have the PPPoE client software installed or the host's operating system should have built-in PPPoE client.
