You can configure up to 16 ISPdomains on the switch. When a user logs in, if no ISP domain name is carried in the username, theswitch assumes that the user belongs to the default ISP domain.z If you have configured to use "." as the delimiter, for a username that contains multiple ".", the first"." will be used as the domain delimiter.z If you have configured to use "@" as the delimiter, the "@" must not appear more than once in theusername. If “.” is the delimiter, the username must not contain any “@”.z If the system does not find any available accounting server or fails to communicate with anyaccounting server when it performs accounting for a user, it does not disconnect the user as longas the accounting optional command has been executed, though it cannot perform accounting forthe user in this case.z The self-service server location function needs the cooperation of a RADIUS server that supportsself-service, such as Comprehensive Access Management Server (CAMS). Through self-service,users can manage and control their account or card numbers by themselves. A server installedwith self-service software is called a self-service server.H3C's CAMS Server is a service management system used to manage networks and ensure networkand user information security. With the cooperation of other networking devices (such as switches) in anetwork, a CAMS server can implement the AAA functions and right management.Configuring an AAA Scheme for an ISP DomainYou can configure either a combined AAA scheme or separate AAA schemes.Configuring a combined AAA schemeYou can use the scheme command to specify an AAA scheme for an ISP domain.Follow these steps to configure a combined AAA scheme:To do… Use the command… RemarksEnter system view system-view —
