Abstract: Methods and systems are described for assigning the proper internet protocol (IP) address to a client device following authentication of the client device on a network. In particular, at commencement of an authentication procedure of the client device, a role is associated with the client device that denies all DHCP renews/requests. By assigning a role to the client device 103 with a “deny DHCP renew/request” rule at the commencement of an authentication procedure, the systems and methods described herein ensure that a race condition does not allow the client device to renew an IP address in an old segment of the network. Accordingly, the client device may avoid a possibly improper IP address in a segment of the network system in which the client device is no longer associated with or operating on.

Abstract: Systems and methods are described that configure network devices to dynamically (1) download privilege setting definitions from an authentication server to address a currently connected set of client devices associated with these privilege setting definitions and (2) clear privilege setting definitions that are no longer in use by client devices connected to the network device. In particular, a network device may determine if a privilege setting definition associated with a successfully authenticated client device is locally available on the network device and request the privilege setting definition from the authentication server when not locally available. In some situations, the authentication server may selectively transmit update messages to network devices that may be affected by an update to a privilege setting definition such that the network devices may request this updated privilege setting definition for download.
