What is adIfPhCurInUnknownProtos1Day?

This OID tracks how many inbound packets arrived with unrecognized or unsupported protocol types during the current 1-day period. Network engineers investigate unknown protocols to discover unauthorized applications, legacy systems, or misconfigured equipment that are sending traffic the device cannot process. For example, if this counter suddenly starts increasing from zero, it may indicate a rogue device or new application running on the network.
