UTHENTICATION
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.
