How is the DTLS license activated on a Cisco Catalyst 9800 controller?

After purchase, register and assign the license in Cisco Smart Software Manager, then use the controller CLI command “license smart enable idtoken ” to activate DTLS.

Can I transfer the DTLS license to a new Cisco Catalyst 9800 controller?

Yes. DTLS licenses are transferable via Cisco Smart Licensing. Deactivate the license on the source device, then reassign it to the target controller in the Smart Software Manager portal.

Is the DTLS license subscription-based or perpetual?

The LIC-C9800-DTLS-K9 is a perpetual license. It requires a valid Cisco SMARTnet or Cisco Catalyst Wireless subscription for ongoing support and software updates.

How do I verify the status of my DTLS license?

On the controller CLI, run “show license all” or “show license summary” to confirm DTLS activation status and expiration (if applicable).

What happens if I deploy a Catalyst 9800 controller without the DTLS license?

Without the DTLS license, controller-to-access-point traffic will fall back to software encryption or remain unencrypted, reducing performance and security.

Does the DTLS license support High Availability deployments?

Yes. The DTLS license extends secure, encrypted DTLS tunnels across both active and standby controllers in HA pairs for uninterrupted failover.

How does DTLS improve wireless network security on the 9800 series?

DTLS provides end-to-end encryption, preventing eavesdropping and tampering on management and data frames exchanged between access points and the controller.

What is the difference between DTLS and TLS on Cisco 9800 controllers?

DTLS is a TLS-based protocol optimized for UDP, delivering low-latency encryption for control plane traffic between access points and the controller.

Can I order the DTLS license online through the Cisco store?

Yes. The LIC-C9800-DTLS-K9 can be ordered directly from the Cisco online store or through the Cisco Commerce Workspace.

How do I troubleshoot DTLS license activation issues?

Ensure device connectivity to Cisco Smart Software Manager, verify token validity with “license smart summary”, and review “show logging” for license errors.

Does the DTLS license SKU include software maintenance?

No. The LIC-C9800-DTLS-K9 provides only the DTLS capability; Cisco SMARTnet or wireless subscription must be purchased separately for maintenance and updates.
