Then the snoopers look up their corresponding cache tag to check whether it has the same cache block. In most cases, the caches do not have the cache block since a well optimized parallel program doesn’t share much data among threads. Thus the cache tag lookup by the snooper is usually an unnecessary work for the cache who does not have the cache block. But t… WebThe CPU uses the sender IP and MAC addresses of the ARP packets, and receiving VLAN and port to create ARP snooping entries. The aging time and valid period of an ARP snooping entry are 25 minutes and 15 minutes. If an ARP snooping entry is not updated within 15 minutes, it becomes invalid and cannot be used. the trip 1967 film wikipedia
