Configuration guidelines

When you configure the RADIUS client, follow these guidelines:
The specified server status is dynamic information, which cannot be saved in the configuration file.
•
After the switch reboots, the status of servers becomes active.
Accounting for FTP users is not supported.
•
If you remove the accounting server used for online users, the switch cannot send real-time
•
accounting requests and stop-accounting messages of the users to the server, and the
stop-accounting messages are not buffered locally.
• For the primary and secondary servers (assume only one secondary server exists) in a RADIUS
scheme, the switch follows these rules to exchange packets with the servers:
If the primary server and secondary server are in the same state, the switch communicates with
the primary server.
If both the primary server and secondary server are in active state, the switch communicates
with the primary server. When the primary server becomes unreachable, the switch sets the
server's status to block and turns to the secondary server for communication. When the quiet
timer expires, the switch changes the status of the primary server to active while keeping the
status of the secondary server unchanged. For authentication and authorization, the switch
resumes the communication with the primary server if the primary server has come back into
operation; in the case of accounting, however, the switch keeps communicating with the
secondary server no matter whether the primary server recovers or not.
If one server is in active state and the other is in block state, the switch only tries to communicate
with the server in active state, even if the server is unreachable.
If both the primary server and secondary server are in block state, the switch only
communicates with the primary server. In this case, if the primary server is reachable, the
switch changes the primary server's status to active. To use the secondary server for
