Hint 1 — Name your vendors and OS versions

Mention the exact platforms you run (Cisco ISE, Aruba ClearPass, NetBox) so the generated nac logic uses the right CLI/NETCONF syntax.

Hint 2 — State your real thresholds

Provide concrete values for NAC target, Identity group, Requests/sec instead of the defaults — they shape what counts as a fault.

Hint 3 — Prioritize the checks you need

This tool can oUI validation and iSE ERS bulk import. 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.
