Manage Guest Network Access

Users with management (admin) credentials—for example, receptionists or hotel clerks—can 
provision guests. Guests need to provide their email address, or both their email address and 
a password. These latter guests are referred to as captive portal users, for which you need to 
set up a captive portal and captive portal user credentials.

Configure Captive Portal Settings

Captive portal authentication is typically used for hotspot users and paying guests such as 
hotel guests who purchase access time for an Internet connection. You can configure a single 
captive portal only per wireless controller.

When you configure a captive portal, you can use either the wireless controller as a local 
authentication server for the captive portal clients, or you can configure an external RADIUS 
server for authentication. There are two types of portal settings:

Guest portal. Use this portal if all wireless users are allowed to access the network by 

supplying only their email address. You do not need to define user names and passwords 
for these users.

Captive portal. Use this portal type if wireless users need to supply their login name and 

password before being allowing access the network. You need to define user names and 
passwords for these users (see 

You cannot configure captive portal authentication if the network 

authentication uses an external RADIUS server. That is, if you 
configure an external RADIUS server with WPA, WPA2, or WPA & 
WPA2 (or if you use legacy 802.1X), you cannot configure captive 
portal authentication; the network authentication needs to be Open 
System, Shared Key, WPA-PSK, WPA2-PSK, or WPA-PSK & 
WPA2-PSK (see 

Note these guidelines for captive portal user authentication and accounting through an 
external RADIUS server:

You can use either the basic-Auth RADIUS server or a RADIUS server of an advanced 

authentication group. You cannot use the external LDAP server.

The wireless controller uses CHAP or MS-CHAP as the authentication protocol with the 

authentication server.

The following RADIUS authentication variables are supported on the wireless controller:

User-Name 

User-Password
