system is called the response timeout timer of RADIUS servers. If the switch gets no
answer within the response timeout time, it needs to retransmit the request to ensure
that the user can obtain RADIUS service.
For the primary and secondary servers (authentication/authorization servers, or
accounting servers) in a RADIUS scheme:
When the switch fails to communicate with the primary server due to some server
trouble, the switch will turn to the secondary server and exchange messages with the
secondary server.
After the primary server remains in the
block
state for a specific time (set by the
timer
quiet
command), the switch will try to communicate with the primary server again when
it has a RADIUS request. If it finds that the primary server has recovered, the switch
immediately restores the communication with the primary server instead of
communicating with the secondary server, and at the same time restores the status of
the primary server to
active
while keeping the status of the secondary server
unchanged.
To control the interval at which users are charged in real time, you can set the real-time
accounting interval. After the setting, the switch periodically sends online users'
accounting information to RADIUS server at the set interval.
