Diagnose interface errors, drops, CRCs, duplex mismatches, flapping, speed negotiation issues, and counter trends on routers, switches, and Linux hosts.
Network Interface Health Use this skill when a network symptom might be caused by a physical link, switch port, cable, transceiver, duplex setting, or congested interface. When to Use A host or VLAN has packet loss, latency spikes, or intermittent reachability. A switch or router interface shows CRCs, runts, giants, drops, resets, or flaps. You need to compare both ends of a link before replacing hardware. A change window needs before/after interface counter evidence. Monitoring reports rising ifInErrors, ifOutErrors, or ifOutDiscards. How It Works Interface counters are evidence, but the trend matters more than the absolute number. Capture a baseline, wait a measurement interval, capture again, then compare increments.
