NOTE:
The maximum number of online portal users the switch actually assi
ns depends on the ACL resources on
the switch.
Specifying an authentication domain for portal users
After you specify an authentication domain for portal users on an interface, the device uses the
authentication domain for authentication, authorization, and accounting (AAA) of all portal users on the
interface, ignoring the domain names carried in the usernames. This allows you to specify different
authentication domains for different interfaces as needed.
To specify an authentication domain for portal users on an interface:

3. Specify an authentication
domain for portal users on the
interface.
portal domain [ ipv6 ]
domain-name
By default, no authentication
domain is specified for portal
users.
The switch selects the authentication domain for a portal user on an interface in this order: the
authentication domain specified for the interface, the authentication domain carried in the username,
and the system default authentication domain. For information about the default authentication domain,
see "Configuring AAA."
Configuring Layer 2 portal authentication to support Web
proxy
By default, proxied HTTP requests cannot trigger Layer 2 portal authentication but are silently dropped.
To allow such HTTP requests to trigger portal authentication, configure the port numbers of the Web
proxy servers on the switch.
If a user's browser uses the Web Proxy Auto-Discovery (WPAD) protocol to discover Web proxy servers,
add the port numbers of the Web proxy servers on the switch, and configure portal-free rules to allow
user packets destined for the IP address of the WPAD server to pass without authentication.
You must add the port numbers of the Web proxy servers on the switch and users must make sure their
browsers that use a Web proxy server do not use the proxy server for the listening IP address of the local
portal server. Thus, HTTP packets that the portal user sends to the local portal server are not sent to the
Web proxy server.
