Captive Portal on a VLAN

A Captive Portal (sometimes referred to as External Web Authentication) can be enabled on any VLAN associated with Flexible authentication (restricted VLAN, guest VLAN, or critical VLAN). You can also enable a Captive Portal on any VLAN which is independent of Flexible authentication configuration. In either case, the client must send HTTP request for the switch to initiate external Web Authentication.

Captive Portal Flow illustrates the Captive Portal flow on a restricted VLAN configured as part of Flexible authentication and a normal VLAN (any VLAN) which is independent of Flexible authentication configuration.
