What is ssiHostUnreachable?
This read-only Counter32 counts ICMP Host Unreachable 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 HostUnreachable count on the monitored segment's ICMP/IP traffic to spot when traffic is repeatedly failing to reach one specific end host rather than an entire network, narrowing the fault to that device. For example, HostUnreachable reports concentrated on one IP address on the monitored segment's ICMP/IP traffic would point the admin at that single host being powered off or disconnected, rather than a broader network issue.
