Abstract
A network switch is comprised of a control processor and one or more line cards. The control processor includes functionality to register interest with a hypervisor, operating in conjunction with a network host connected to the switch, in data object attributes maintained on the network host by the hypervisor. The hypervisor associated with the network host sends changes in the host attributes to the switch which the switch maintains in a listing of attributes. The switch traps and copies particular packets to the switch control processor where a provisioning function operates on the attribute information in the list with source information included in the packet header in order to configure a forwarding table on the line card.
