Domain-Based User Management
An Internet service provider (ISP) domain accommodates a collection of users. NAS devices manage
users based on ISP domains. Each user belongs to an ISP domain. The ISP domain of a user is
determined by the username used for login, as shown in Figure 1-7 .
Figure 1-7 Determine the ISP domain of a user by the username
The authentication, authorization, and accounting of a user depends on the AAA methods configured
for the domain that the user belongs to. If no specific AAA methods are configured for the domain, the
default ones are used. By default, a domain uses local authentication, local authorization, and local
accounting.
The AAA feature allows you to manage users based on their access types:
z LAN users: Users on a LAN who must pass 802.1X authentication or MAC address authentication
to access the network.
z Login users: Users who want to log in to the device, including SSH users, Telnet users, FTP users,
and terminal service users.
