Web Authentication

Web authentication allows stations to authenticate and access the network in situations where
802.1X or Network Access authentication 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 user
name and password authentication via RADIUS. Once authentication is successful, the web
browser is forwarded on to the originally requested web page. Successful authentication is valid for
all hosts connected to the port.

NOTE

RADIUS authentication must be activated and configured for the web authentication feature to work
properly (see

“Authentication Sequence”

on page 144).

Web authentication cannot be configured on trunk ports.
