What is ssiDestHostUnknown?
This read-only Counter32 counts ICMP Destination Host Unknown report frames seen on the monitored segment's ICMP/IP traffic during this 15-second short-term sample, with 4294967294 meaning unknown. An admin uses a rising DestHostUnknown count on the monitored segment's ICMP/IP traffic to catch traffic aimed at an end host address that the network genuinely has no route to, distinct from a host that is merely offline. For example, a persistent DestHostUnknown count for one address on the monitored segment's ICMP/IP traffic might indicate a stale DNS or ARP entry still pointing clients at a retired host address.
