This is a write-only control object: setting it to reset(1) clears both the total-received and dropped-packet URPF counters for this VLAN interface back to zero, while reading it always returns 0 regardless of when it was last used. Administrators use this to establish a clean counter baseline after resolving a spoofing incident or after changing URPF-related configuration on the interface. For example, an admin who just addressed a spoofing attack and confirmed it's resolved might set this to reset(1) to clear the elevated dropped-packet counter and start fresh monitoring from zero.
