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 username 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.
