(Optional) Configuring the User Authentication Domain

Context

When the MAC address or the fixed user name without a domain name is used as the user name in MAC address authentication, the user is authenticated in a default domain if the administrator does not configure an authentication domain. In this case, many users are authenticated in the default domain, making the authentication scheme inflexible.

The authentication domain for the MAC address authentication user can be configured globally or on an interface.

When configured globally, the authentication domain is valid for all interfaces.
When configured on an interface, the authentication domain is valid for this interface only. The priority of the user name configured on the interface is higher than that of the user name configured globally. If no authentication domain is configured on the interface, you can use the globally configured authentication domain.

When the fixed user name is used for MAC address authentication and the authentication domain is specified in the user name, the user is authenticated in the specified authentication domain.
Before configuring an authentication domain for the MAC address authentication user, ensure that the authentication domain has been created.

Procedure

In the system view:
1. Run system-view
  The system view is displayed.
2. Run mac-authen domain isp-name [ mac-address mac-address mask mask ]
  The authentication domain is configured for the MAC address authentication user.
  
  By default, MAC address authentication uses the global default domain.
In the interface view:
1. Run system-view
  The system view is displayed.
2. Run interface interface-type interface-number
  The interface view is displayed.
3. Run mac-authen domain isp-name
  The authentication domain is configured for the MAC address authentication user.
  
  By default, MAC address authentication uses the global default domain.
