Hint 1 — Name your vendors and OS versions

Mention the exact platforms you run (Cisco IOS/XE, Juniper Junos, MikroTik) so the generated isp & peering logic uses the right CLI/NETCONF syntax.

Hint 2 — State your real thresholds

Provide concrete values for DHCP DNS server, Output directory instead of the defaults — they shape what counts as a fault.

Hint 3 — Prioritize the checks you need

This tool can day-0 CPE template and wAN/LAN + NAT + DHCP. Ask for the subset relevant to your incident to keep output focused.

Hint 4 — Describe your inventory format

Tell the assistant whether your device list is CSV, YAML, or JSON and which columns it has, so parsing matches your data.

Sample inventory schema

Authoritative shape of the device/policy data this script consumes.

No bundled inventory sample. The script accepts standard device lists (CSV/YAML) with hostname, mgmt IP, vendor, and credentials.

Expected output

Reference terminal output the script should produce — used as a stylistic and structural target.
