Abstract

A technique for verifying an intermediate node that employs a forwarding plane (572a, 572b) and optionally a control plane (592a, 592b). A test packet is generated and transferred to the for­warding plane (572a, 572b). Using operational software and hardware, the forwarding plane (572a, 572b) for­wards the test packet to a line card (512a, 512b), which in turn 'loops' (700a, 700b, 700c) the test packet back to the forwarding-plane (572a, 572b). Using operational software and hardware, the forwarding plane (572a, 572b) pro­cesses the looped-back test packet including forwarding the packet to a destination, such as a control plane (592a, 592b), where the looped-back test packet is verified.
