218 CHAPTER 9: AAA AND RADIUS OPERATION
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 an environment, one access device might access
users of different ISPs. Because the attributes of ISP users, such as username
support and password formats, etc., are usually different, it is necessary to group
them by setting ISP domain. In the Switch 7750 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 server group applied etc.)
For the Switch 7750, each supplicant belongs to an ISP domain. Up to 16 domains
can be configured in the system. If a user has not reported its ISP domain name,
the system will put it into the default domain.
Perform the following configurations in system view.
By default, the domain name system is already created. The attributes of system
are all default values.
Configuring Relevant Attributes of an ISP Domain
The relevant attributes of an ISP domain include the adopted RADIUS server
group, state, and maximum number of supplicants. Note the following:
■ The adopted RADIUS server group is the one used by all the users in the ISP
domain. The RADIUS server group can be used for RADIUS authentication or
accounting. By default, the default RADIUS server group is used. For details,
refer to
“Configuring the RADIUS Protocol ”.
■ Every ISP has active/block states. If an ISP domain is in active state, the users
can request for network service, while in block state, users cannot request any
network service. An ISP is in the block state when it is created.
■ Maximum number of supplicants specifies how many supplicants can be
contained in the ISP. By default, for any ISP domain, there is no limit to the
number of supplicants.
■ The idle cut function means that if the traffic from a certain connection is lower
than the defined traffic, cut off the connection.
Perform the following configurations in ISP domain view.
