5.13.3 Web Authentication
Web authentication allows stations to authenticate and access the network in situations where 802.1X or Network Access
authentication methods 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 “RADIUS Client” on page
4-88.)
2. Web authentication cannot be configured on trunk ports.

login attempts until the quiet time expires. Use the no form to restore the default.
