Cisco DNA Advantage C6840 Low SMS-K | Cisco Licensing, Renewal — C6840-DA-L-SMSK

Keep Cisco C6840 environments covered with renewal-only DNA Advantage licensing built for organizations that already standardized on Cisco infrastructure. This entitlement is designed to preserve access to advanced software-defined networking capabilities, helping teams maintain policy consistency, operational visibility, and centralized management without disrupting established deployments. For infrastructure groups managing long-lived access and aggregation layers, the value is continuity. Rather than requalifying the platform or changing the operating model, this license extends the software framework that supports day-to-day control and network governance. That matters when uptime, configuration discipline, and lifecycle planning carry more weight than feature churn. Cisco DNA Advantage is typically chosen when the network must do more than pass traffic. It supports the operational model behind segmentation, automation, and assurance workflows that reduce manual intervention and help teams respond faster to change. The low SMS-K designation indicates a specific commercial entitlement for renewal scenarios, making it a fit for organizations protecting prior investment in Cisco architecture.
