What is adIfPh15MinInUnknownProtos?
This OID counts packets arriving on the interface using unrecognized or unsupported protocols during each 15-minute window. Engineers watch for unknown protocols to catch misconfigured devices, legacy systems running unexpected protocols, or potential security threats. A spike from zero to 50 unknown protocol packets in 15 minutes could indicate a newly connected rogue device or configuration error.
