Configure the normal authorization network segment a and the low permission network segment b on the authentication server, and obtain different network segments through login success and failure. When the user connects to the network to obtain the b address, after successful authentication, it is still the b address, and needs to be unplugged and reconnected to refresh to the a address. The authentication server is Aruba's cppm, and it can be seen that the message matches the correct network segment. Is there any case or explanation for this problem
