When the primary server and secondary servers are all in the blocked state, the device
communicates with the primary server. If the primary server is available, its statues changes
to active. Otherwise, its status remains to be blocked.
If one server is in the active state but all the others are in the blocked state, the device only
tries to communicate with the server in the active state, even if the server is unavailable.
After receiving an authentication/accounting response from a server, the device changes
the status of the server identified by the source IP address of the response to active if the
current status of the server is blocked.
• Set the real-time accounting interval based on the number of users.
