The error code NCSW10301 typically appears in Cisco Catalyst Center (formerly DNA Center) when using the Software Image Management (SWIM) feature to automate downloads from Cisco.com. The full error—"Unable to download the image from cisco.com: invalid metadata_trans_id"—indicates a breakdown in the API handshake between your local appliance and Cisco’s software servers. Understanding the Root Cause

The metadata_trans_id is a unique transaction ID generated for each software request, typically expiring within 60 minutes. When Catalyst Center reports this as "invalid," it generally stems from one of three issues:

Third-Party API Instability: Sporadic issues with external providers that handle the APIs for automated downloads.

Expired Certificate Chains: If the trustpool certificates on your Catalyst Center appliance are outdated or expired, the encrypted communication with api.cisco.com fails.

ISSU Compatibility Matrix Failures: In some cases, the main image downloads successfully, but the associated In-Service Software Upgrade (ISSU) metadata fails to sync, triggering the error. Step-by-Step Troubleshooting and Workarounds 1. Manual Image Import (Immediate Workaround)

If you need to upgrade a device immediately and cannot wait for API resolution, bypass the automated system by manually importing the image:

Download the required .bin or .tar image to your local workstation. In Catalyst Center, navigate to Design > Image Repository. Click Import and upload the file from your computer. 2. Check Certificate Trustpools

Cisco frequently updates the certificate authorities (CAs) used for secure API calls. If your appliance is running an older version, it may not recognize the new Cisco.com certificates.

Action: Review Field Notice FN74033, which addresses critical certificate updates required for Catalyst Center to communicate with Cisco servers after April 2024. 3. Verify Proxy and Firewall Settings

The Image Repository may sometimes bypass configured proxy settings, attempting a direct connection that gets blocked by your firewall.

Check: Run a packet capture (TCPDUMP) on the Catalyst Center appliance to see if it is attempting to reach cloudsso.cisco.com or api.cisco.com directly rather than through your proxy.

Allowlist: Ensure the following URLs are permitted through your firewall: *.cisco.com cloudsso.cisco.com swapi.cisco.com 4. Re-sync Cisco.com Credentials

Sometimes the session token between Catalyst Center and your Smart Account becomes stale.

The error NCSW10301: Unable to download the image from cisco.com : invalid metadata_trans_id is a common issue encountered in Cisco Catalyst Center (formerly DNA Center) during Software Image Management (SWIM) operations. This error typically indicates a failure in downloading the associated ISSU Compatibility Matrix (comp_matrix.xml) even if the base image file downloads successfully. Root Causes of NCSW10301

External API Failures: Cisco has identified that certain external providers used for metadata APIs occasionally experience sporadic outages, causing this specific "invalid metadata" response.

Software Bugs: Several bugs have been tracked for this behavior, including CSCwd15921, which affects releases 2.2.3.x through 2.3.4.x.

Registration & Approval Issues: Newer versions like 2.3.7.9 may trigger this error if the product is not properly registered or approved to call Cisco cloud services.

Certificate Expiration: Expired certificates in the Catalyst Center Trustpool can break the secure communication required to fetch metadata from software.cisco.com. The error "NCSW10301: Unable to download the image

Proxy Configuration: If the appliance is behind a proxy and the SWIM engine is not correctly utilizing the proxy settings, metadata requests will fail. Step-by-Step Troubleshooting and Fixes 1. Manual Image Import (The Guaranteed Workaround)

If the automated download fails, the most reliable fix is to manually upload the image:

Download Locally: Go to the Cisco Software Download portal on your laptop and download the required .bin or .tar file.

Import to Catalyst Center: In Catalyst Center, navigate to Design > Image Repository and use the Import function to upload the file from your local machine.

Verify Integrity: Once imported, check System > Settings > Integrity Verification to ensure the image is verified against Known Good Values (KGV). 2. Refresh Cisco.com Credentials

Sometimes the token between your appliance and Cisco's servers becomes "invalid": Go to System > Settings > Cisco.com Credentials.

Remove the existing account and re-add it using your Cisco Smart Account credentials. 3. Update the Trustpool

Metadata downloads require valid root certificates to verify Cisco's servers: Navigate to Settings > Trust & Privacy > Trustpool.

Check if there is a pending update for the Cisco Trustpool and apply it to restore secure communications. 4. Verify Proxy and Connectivity

Ensure the appliance can actually reach the metadata endpoints:

Use the CLI to test connectivity to cloudsso.cisco.com and software.cisco.com.

Check if your firewall is blocking traffic to these URLs or if the appliance is attempting to bypass the configured proxy for SWIM tasks. 5. Check for Known Field Notices

Cisco released Field Notice FN74033, stating that older versions of DNA Center will fail to download metadata after April 26, 2024, due to certificate changes. If you are on an older release, an upgrade to a fixed version (e.g., 2.3.5.x or later) is required.

Understanding the Error

ncsw10301: This seems to be a specific error or code related to network conversion or a particular process you're trying to execute. It might be model-specific or related to a network converter tool.
Unable to download the image from cisco.com: The primary issue here is that your system or tool is unable to retrieve an image (likely a firmware, software, or configuration file) from Cisco's official website.
Invalid metadata: Metadata is "data that provides information about other data". In this context, the system is likely receiving metadata that it cannot interpret correctly, possibly due to a corruption, incorrect formatting, or miscommunication during the download process.
trans-id: This could refer to a unique identifier for your transaction or session, which might be useful for tracking or troubleshooting purposes.

4.2 Why Trans-ids Expire Quickly

Cisco implements short-lived transaction tokens to:

Prevent unauthorized or disconnected download links from being shared.
Ensure that each download is preceded by a fresh metadata check (which enforces license compliance and export restrictions).
Reduce load from stale client retries.
