What is cnt2XIfInUnknownProtos?
This Counter32 counts inbound packets discarded because of an unknown or unsupported protocol, tracked here for the extended-table interface. An administrator investigates a nonzero value as unexpected protocol traffic reaching a port that was configured to carry something else. For example, cnt2XIfInUnknownProtos incrementing on an interface expected to carry only IP traffic hints that stray legacy-protocol frames are still arriving on it.
