1x is inconsistent across devices, even between devices of the same OS. Select this option to override any user-defined reauthentication interval and use the reauthentication period defined by the authentication server. However, the client can be assigned a derived VLAN upon successful user authentication. This parameter instructs the controller to check the pairwise master key (PMK) ID sent by the client.
