Usage Scenario
If a user goes offline due to a power failure or network interruption, the authentication access device and authentication control device may still store information about this user, which results in a heavy load on the authentication control device. In addition, a limited number of users can access the device. If a user goes offline unexpectedly but the device still stores information of this user, other users cannot access the network.
After the detection interval is set, the device considers a user to be offline if the user does not respond within the interval. Then the authentication access device and authentication control device delete the saved information about the user, ensuring effective resource usage.
Precautions
This command is supported only on authentication access devices.
