What is iliProtocolUnreachable?
ProtocolUnreachable is a read-only Counter32 counting the number of Protocol Unreachable report frames recorded for this IP host; a value of 4294967294 means the count is unknown rather than a genuine zero. This counter matters to an admin because it isolates a destination reporting that it does not support the IP protocol number a packet was sent with, letting them see that specific condition trending up without having to sift through every ICMP message the host or pair exchanged. If ProtocolUnreachable for host 10.4.12.30 starts climbing while other ICMP counters in the same row stay flat, that isolated rise points specifically at a destination reporting that it does not support the IP protocol number a packet was sent with rather than a general ICMP flood.
