Question

An engineer uses an AI coding assistant to generate a Python script that pushes an interface description change via RESTCONF to a Cisco IOS XE device. The generated code targets the YANG path /restconf/data/Cisco-IOS-XE-native:native/interface/GigabitEthernet=1%2F0%2F1/description-text. When executed against the lab device, the request returns HTTP 400 with a 'unknown-element' error, even though the credentials, TLS bundle, and connectivity are all confirmed working. Before deploying to production, what is the MOST appropriate action to validate the AI recommendation?

Accepted Answer

Verify the generated leaf name against the device's actual YANG model (e.g., via the RESTCONF schema/YANG library or 'show' of supported models), since the AI may have hallucinated 'description-text' instead of the valid 'description' leaf

Answer

Trust the AI output and retry the request, since HTTP 400 errors on RESTCONF are typically transient and clear after a token refresh

Answer

Switch the HTTP method from PATCH to PUT, because a 400 error indicates the resource must be fully replaced rather than merged

Answer

Disable TLS certificate verification in the request so the payload reaches the device without transport-layer interference
