Captive Portal Profile for External Web Authentication
The Captive Portal profile serves as a template that includes configuration details
specific to the external server such as virtual IP address, HTTP or HTTPS protocol
port number, and details of the login page hosted on the NAC server.
Note: The terms Captive Portal and external Web Authentication are used interchangeably.
The details configured in the Captive Portal profile enable the switch to handle the HTTP redirection mechanism and redirect the client to the login page hosted on the NAC server. The Captive Portal profile is then applied on an external Web Authentication-enabled VLAN.
