Catalyst 9000 DNA License Installation Guide
This guide provides a detailed and professional tutorial for installing DNA licenses on Cisco Catalyst 9000 switches using DNA tokens.
Prerequisites
1. **Access Requirements**:
– Ensure you have administrative access to the Catalyst 9500 device.
– Ensure access to the Cisco Smart Software Manager (CSSM).
2. **Obtain a Registration Token**:
– Log in to CSSM: [https://software.cisco.com/](https://software.cisco.com/)
– Navigate to **Smart Software Licensing** > **Manage** > **Tokens**.
– Click **Generate Token**, configure the necessary settings (e.g., expiration period and device binding description), and generate the registration token.
3. **Network Connectivity**:
– The Catalyst 9500 must have internet access or be configured to use a proxy or local license server.
4. **Time Synchronization**:
– Ensure the device’s system time is accurate. Use an NTP server for time synchronization.

Configuration Steps #
1. Enable Smart Licensing
Enable smart licensing on the device.
“`plaintext
2. Configure Call Home
configure terminal
license smart enable
end
Call Home facilitates communication with CSSM. Configure it as follows:
configure terminal
service call-home
call-home
profile CiscoTAC-1
destination transport-method http
destination address http https://tools.cisco.com/its/service/oddce/services/DDCEService
end
Note:
• Adjust the destination address if using a proxy or local license server.
• Ensure the device can resolve DNS names successfully.
3. Register the Device
Use the registration token generated in CSSM to register the device.
license smart register idtoken <your-registration-token>
Example:
license smart register idtoken ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890
The device will connect to CSSM and attempt to acquire the necessary licenses.
4. Verify License Status
After registration, verify the license status:
show license status
The output should indicate the following:
• Smart Licensing Status: Registered
• License Authorization: Authorized
Troubleshooting
1. Device Cannot Connect to CSSM
• Ensure the device has a stable internet connection.
• Verify the Call Home configuration.
• If using a proxy, ensure the proxy’s IP address and port are correctly configured.
2. Registration Token Expired
• Log in to CSSM and generate a new registration token.
• Use the new token to re-register the device.
3. License Status Shows “Out of Compliance”
• Check whether licenses are assigned to the device.
• Log in to CSSM and verify the license allocation to ensure sufficient licenses are available for the Catalyst 9500.
Best Practices and Notes
1. Maintain License Compliance:
• Ensure the device periodically synchronizes with CSSM to stay compliant.
2. Use a Local License Server:
• For environments without direct internet access, configure Cisco Smart Licensing Satellite as a local license server.
3. Security:
• Secure your network environment to prevent unauthorized access or token leakage.
