After preferential access of VIP users is configured on a device, if the number of access users on a VAP reaches the maximum value or the user CAC threshold, the network access attempt of new users will trigger the following process:
1. A user is authenticated.

is a VIP user in the authorization phase.
- If so, the system forcibly disconnects an online non-VIP user and
allows the VIP user to access the network.
- If not, the system denies the user's network access attempt.
