ABSTRACT:
In one embodiment, an apparatus comprises one or more forwarding logic components and logic coupled to a plurality of network interfaces. The logic is operable to: receive address information that identifies a packet flow; generate a synthetic packet based on the address information; provide the synthetic packet to the one or more forwarding logic components; retrieve forwarding information that indicates one or more forwarding decisions for the synthetic packet made by the one or more forwarding logic components; and report the forwarding information. Each of the one or more forwarding logic components is operable to make a forwarding decision for the synthetic packet as part of processing packets in the packet flow, and to store, as part of the forwarding information, data indicating the forwarding decision for the synthetic packet that is made by that forwarding logic component.
