Abstract
A network switch having hardware thereon for transmitting probes to neighbor devices for exercising forwarding states (e.g., layer 2 and layer 3) on the switch. A light-weight agent resides on one or both of neighbor network devices and can be used to control the testing. One or more probes originating from the source network device (device A) from a local CPU are routed on the same network device A in hardware and sent out on a link towards a peer device (device B). Peer device B captures the probe using an Access Control List (ACL) hardware, and transmits the probes to a local agent for processing. The agent then transmits the probe back to the source network device and the source network device can determine whether the FIB lookup was correctly performed.
