Patent ID: 8752160

Claim:
A dynamic network interfaces system, comprising: an at least one computer system; and a dynamic network interfaces application that, when executed on the at least one computer system: determines that a client device requesting a network service is a member of a group, wherein members of the group are associated with a single virtual local area network tag, determines that the client device is the first member of the group to request access to the network service, obtains subnet interface information from a subnet interface pool and the virtual local area network tag from a virtual local area network tag pool, wherein the virtual local area network tag is randomly selected from the virtual local area network tag pool and is unrelated to, and randomly combined with, the subnet interface information, sends to an access device and a firewall device the subnet interface information from the subnet interface pool, the virtual local area network tag from the virtual local area network tag pool, physical interface designations, and instructions to configure a subnet interface using the subnet interface information and the virtual local area network tag and associate the subnet interface with the designated physical interfaces on the access device and the firewall device to provision a virtual local area network, activates the virtual local area network in response to receiving at least one message from the access device and the firewall device indicating that the subnet interface has been configured on each device and associated with the virtual local area network tag and the designated physical interfaces.
