Abstract: A policy server correlates information from several messages associated with a client device to implement an identity-based network access policy. A network element connected to the client device obtains an authentication message including a first network address from the client device. The network element provides the authentication device to an identity server via a Network Address Translation (NAT) device, which translates the first network address to a second network address. The network element also provides a first message including the first network address to the policy server to request an identity-based policy for network communications of the client device. The network element implements the identity-based policy authorized by the policy server.

Abstract: Address support and network address transparency may be provided. First, a border device may receive a processed network configuration parameter request having an address of a subnet to which a client device is associated and information data in an information field of the network configuration parameter request. The information data may comprise an address of a network device and an identifier of the subnet to which the client device is associated. Next, the border device may encapsulate the processed network configuration parameter request with the information data extracted from the processed network configuration parameter request. The border device may then forward the encapsulated network configuration parameter response to the network device.

Abstract: A policy server correlates information from several messages associated with a client device to implement an identity-based network access policy. The policy server receives a first message from a network element connected to the client device. The first message requests an identity-based policy for the client device, and includes a first network address. The policy server receives a second message from an identity server. The second message includes information indicating an identity role and a second network address. The policy server receives a third message from a NAT device. The third message includes a NAT mapping that correlates the first network address with the second network address. After the policy server determines the identity-based policy based on a combination of the first message, the second message, and the third message, the policy server implements the identity-based policy in the network element.

Abstract: A network device includes ports to communicate with and provide power to devices connected thereto. The network device serves access points (APs) that connect wirelessly to client devices. The network device detects that a client device has wirelessly connected to or disconnected from an AP that is connected to the network device. Responsive to the detecting, the network device accesses predetermined power control information associated with the client device. If the power control information identifies one or more of the multiple ports, the network device selectively provides power to the identified one or more ports when the client device is detected as being connected to the AP and removes power from the identified one or more ports when the client device is detected as not being connected to the AP.
