Why Online User Information Cannot Be Displayed or Users Are Forced to Go Offline When a Switch Connects to the Agile Controller-Campus or Policy Center Server?

If the server cannot display information about online users when a device connects to the Agile Controller-Campus or Policy Center server, a possible cause is that no accounting scheme is configured on the device.
If users are forced to go offline when a device connects to the Agile Controller-Campus or Policy Center server, possible causes are as follows:
- The interim accounting interval configured on the device is short, yet many access users connect to the device.
- The interim accounting interval configured on the server is different from that configured on the device.
