Writing clear(1) to this object is a SET command that resets all of the IP routing statistics counters (packet totals and drop counters) back to zero. This is the maintenance action an admin performs after resolving a drop-reason issue, such as adding a missing route, so that subsequent monitoring reflects the fixed state rather than being polluted by the historical spike in a specific drop counter. After tracking down and fixing a bad ARP-related packet loss, a technician would SET this object to 1 to zero out the affected counters before starting a clean monitoring baseline.
