Configuration Guide
Perform the following configuration in ISP domain view.
Table 2-8 Configure an access limit
Set an access limit to limit the number of
users
accommodate.
Restore the default value.
By default, an ISP domain has no limit on the user number upon its creation.
V. Enabling accounting optional
If a user is configured with accounting optional, the router does not disconnect the
user during the accounting even when it finds no available accounting server or fails to
communicate with the accounting server.
Unlike the scheme none command, with the accounting optional command, the
system sends accounting information to the accounting server but does not terminate
the connection regardless of whether the accounting server responds or performs the
accounting service. However, with the scheme none command, the system neither
sends accounting information to the accounting server nor terminates the connection. If
you specify RADIUS or HWTACACS in the scheme command without configuring
accounting optional, the system sends accounting information to the accounting
server and if the server does not respond or perform accounting service terminates the
connection.
Perform the following configuration in ISP domain or RADIUS view.
Table 2-9 Enable/disable accounting optional
Enable accounting optional.
Disable accounting optional.
By default, when an ISP domain is created, accounting optional is disabled.
VI. Defining an address pool and allocating IP addresses to PPP domain users
PPP users can obtain IP addresses from the router through PPP address negotiation.
Three approaches are available for address allocation on an interface:
Directly allocate IP addresses on the interface without configuring an address
pool.
