Ncsw10301 Unable To Download The Image From Cisco.com Invalid Metadata Trans-id

| Error Code | Likely Cause | Fix | |------------|--------------|------| | NCSW10300 | Network timeout | Check firewall/proxy | | NCSW10301 | Invalid trans-id | Clear cache, sync time | | NCSW10302 | Checksum mismatch | Re-download image | | HTTP 403 Forbidden | Smart Account issue | Re-authenticate CCO |

Ensure NCS can reach Cisco’s servers:

curl -I https://software.cisco.com/download/home/

Check for HTTP 200 OK. Also verify your Cisco Smart Account credentials are correctly stored in NCS (for CCO authentication). | Error Code | Likely Cause | Fix

If the error persists, bypass NCS automation: Ensure NCS can reach Cisco’s servers: curl -I

This avoids the trans-id validation entirely. Check for HTTP 200 OK

After re-authentication, wait 5 minutes for token propagation, then retry the download.

In automation scripts using NCS APIs, implement exponential backoff:

for attempt in range(3):
    try:
        download_image(image_id)
        break
    except NCSW10301:
        refresh_metadata()
        time.sleep(30 * (attempt + 1))
