What is sliNetUnreachable?
This read-only Counter32 counts ICMP Network Unreachable report frames seen on the monitored segment's ICMP/IP traffic during this 15-minute long-term sample, with 4294967294 meaning unknown. An admin treats a rising NetUnreachable count on the monitored segment's ICMP/IP traffic as a sign that a router in the path has lost a route to some destination network, worth cross-checking against recent routing changes. For example, a spike in NetUnreachable reports on the monitored segment's ICMP/IP traffic right after a link outage elsewhere in the network would confirm that outage is affecting reachability to that entire remote network.
