Redundancy Validation Engine

Comprehensive redundancy verification: HSRP/VRRP/GLBP state audit, automated failover testing with convergence measurement, single-point-of-failure detection via topology graph analysis, and SLA impact scoring.

Required inputs

Parameters the script accepts. Defaults shown; some are vendor- or context-gated.

Parameter	Type	Default	Notes
Check HSRP/VRRP check_hsrp	bool	true	—
Check LACP check_lacp	bool	true	—

Hint 1 — Name your vendors and OS versions

Mention the exact platforms you run (cisco-ios, cisco-nxos, arista) so the generated fault logic uses the right CLI/NETCONF syntax.

Hint 2 — State your real thresholds

Provide concrete values for Check HSRP/VRRP, Check LACP instead of the defaults — they shape what counts as a fault.

Hint 3 — Prioritize the checks you need

This tool can hSRP and vRRP. 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.
