4.11.11 Web Authentication
Web authentication allows stations to authenticate and access the network in situations where 802.1X or Network Access
authentications are infeasible or impractical. The web authentication feature allows unauthenticated hosts to request and
receive a DHCP assigned IP address and perform DNS queries. All other traffic, except for HTTP protocol traffic, is blocked. The
switch intercepts HTTP protocol traffic and redirects it to a switch-generated web page that facilitates username and password
authentication via RADIUS. Once authentication is successful, the web browser is forwarded on to the originally requested web
page.
1. RADIUS authentication must be activated and configured properly for the web
authentication feature to work properly. (See “Configuring Local/Remote Logon
Authentication” on page 3-58)
2. Web authentication cannot be configured on trunk ports.
