Device Roles
With web-based authentication, the devices in the network have these specific roles:
•
Client —The device (workstation) that requests access to the LAN and the services and responds to
requests from the switch. The workstation must be running an HTML browser with Java Script
enabled.
• Authentication server —Authenticates the client. The authentication server validates the identity of
the client and notifies the switch that the client is authorized to access the LAN and the switch
services or that the client is denied.
•
Switch —Controls the physical access to the network based on the authentication status of the client.
The switch acts as an intermediary (proxy) between the client and the authentication server,
requesting identity information from the client, verifying that information with the authentication
server, and relaying a response to the client.
Figure 10-1 shows the roles of these devices in a network:

Host Detection
The switch maintains an IP device tracking table to store information about detected hosts.
Note By default, the IP device tracking feature is disabled on a switch. You must enable the IP device tracking
feature to use web-based authentication.
