Error: Request not implemented when running NCM capture action via vnmsh update

Issue/Introduction

When attempting to trigger a Network Configuration Manager (NCM) capture using the vnmsh update command, the action fails with the error update: Request not implemented. This occurs when using an invalid or deprecated action code.

Environment

• DX NetOps Spectrum
• Network Configuration Manager (NCM)

Cause

The error occurs because the action code provided (e.g., 0x50e000) is not for a single device model handle, but for a NCM device family.

Resolution

Use the correct action codes to initiate NCM captures via CLI.

For a single device capture: Use action code 0x821001 (CAPTURE_HOST_CONFIG).

 

./update action=0x821001 mh=(single device model handle)

 

For a device family capture: Use action code 0x50e0002 (Capture Configuration).

 

./update action=0x50e0002 mh=(device family model handle)
