AAA Configuration
The following sections describe AAA configuration tasks.
Among the above configuration tasks, creating ISP domain is compulsory; 
otherwise the supplicant attributes cannot be distinguished. The other tasks are 
optional. You can configure them at requirements.
Creating/Deleting an ISP 
Domain
What is Internet Service Provider (ISP) domain? To make it simple, ISP domain is a 
group of users belonging to the same ISP. Generally, for a username in the 
userid@isp-name format, taking gw20010608@3Com163.net as an example, the 
isp-name (i.e. 3Com163.net) following the @ is the ISP domain name. When 
3Com Series Switches control user access, as for an ISP user whose username is in 
userid@isp-name format, the system will take userid part as username for 
identification and take isp-name part as domain name.
The purpose of introducing ISP domain settings is to support the multi-ISP 
application environment. In such environment, one access device might access 
users of different ISP. Because the attributes of ISP users, such as username and 
password formats, etc, may be different, it is necessary to differentiate them 
through setting ISP domain. In 3Com Series Switches ISP domain view, you can 
configure a complete set of exclusive ISP domain attributes on a per-ISP domain 
basis, which includes AAA policy (RADIUS scheme applied etc.)
