To do… Use the command… Remarks
Enable buffering of
stop-accounting requests to
which no responses are
received
stop-accounting-buffer enable
Optional
Enabled by default
Set the maximum number of
stop-accounting attempts
retry stop-accounting retry-times
Optional
500 by default
NOTE:
• The IP addresses of the primary and secondary accounting servers must be different from each other.
Otherwise, the configuration fails.
• All servers for authentication/authorization and accountings, primary or secondary, must use IP
addresses of the same IP version.
• If you delete an accounting server that is serving users, the device can no longer send real-time
accounting requests and stop-accounting requests for the users to that server, or buffer the
stop-accounting requests.
• You can specify a RADIUS accounting server as the primary accounting server for one scheme and as
the secondary accounting server for another scheme at the same time.
• RADIUS does not support accounting for FTP users.
Specifying the shared keys for authenticating RADIUS packets
The RADIUS client and RADIUS server use the MD5 algorithm to encrypt packets exchanged between
them and use shared keys to authenticate the packets. They must use the same shared key for the same
type of packets.
A shared key configured in this task is for all servers of the same type (accounting or authentication) in
the scheme, and has a lower priority than a shared key configured individually for a RADIUS server.
Follow these steps to specify shared keys for authenticating RADIUS packets:
To do… Use the command…

Required
No shared key by default
NOTE:
A
shared key configured on the device must be the same as that configured on the RADIUS server.
Setting the username format and traffic statistics units
A username is usually in the format of userid@isp-name, where isp-name represents the name of the ISP
domain the user belongs to and is used by the device to determine which users belong to which ISP
domains. However, some earlier RADIUS servers cannot recognize usernames that contain an ISP
domain name. In this case, the device must remove the domain name of each username before sending
the username. You can set the username format on the device for this purpose.
