Web-Based Authentication
  
  
    This section describes web-based network login.
    For web-based 
      authentication, you
      need to configure the switch DNS name, default redirect page, session refresh, and
      logout-privilege. URL redirection requires the switch to be assigned a DNS name. The default
      name is network-access.com. Any DNS query coming to the switch to resolve switch DNS name in
      unauthenticated mode is resolved by the DNS server on the switch in terms of the interface (to
      which the network login port is connected). 

Note   
When both HTTP and
        HTTPS are enabled on the switch and sending HTTP requests from the Netlogin client, HTTPS
        takes preference and the switch responds with a HTTPS response.
