Use this skill when a network symptom might be caused by a physical link, switch
port, cable, transceiver, duplex setting, or congested interface.
- 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`.
