1. A method comprising: detecting, by a network node, a presence of a first server device on a network associated with the network node; communicating, by the network node, with the first server device to obtain information associated with the first server device; sending, by the network node and to a second server device, a request for authentication services, receiving, by the network node and from the second server device, a notification that the first server device has been authenticated, establishing, by the network node and based on the notification, a session with the first server device, checking, at a later point in time, the session information stored in the memory; determining whether the first server device is the particular type of server device based on the information associated with the first server device and the session threshold; disassociating the first server device and the VLAN when the first server device is not the particular type of server device; and maintaining an association between the first server device and the VLAN when the first server device is the particular type of server device and the later point in time is within the period of time.
