Cisco ONE DNA Advantage C3850 12-Port Fiber Renewal | Term License — C38503-DNAC1A-1R

Keep your Catalyst 3850 fiber deployment under active entitlement with this renewal-only Cisco ONE Digital Network Architecture Advantage term license. Built for an installed 12-port switch, it extends access for teams that need to preserve existing licensing coverage without changing the underlying hardware footprint. This 1-year validation period is designed for organizations that already standardized on Cisco DNA Advantage and want to maintain continuity across network operations, policy management, and lifecycle planning. It is not a new deployment license; it is specifically intended for renewal use, which makes it a precise fit when procurement needs to extend coverage on an in-service switch rather than relicense the environment. For infrastructure teams managing campus access layers, fiber uplinks, or branch switching estates, renewal-only licensing helps avoid gaps in entitlement while keeping the installed base aligned with Cisco’s software framework. The result is cleaner compliance, simpler renewal planning, and less disruption for networks that still depend on Catalyst 3850 hardware. Ideal For Renew licensing for an in-service Catalyst 3850 switch with 12 fiber ports Maintain entitlement continuity during annual procurement cycles Extend Cisco DNA Advantage coverage for an existing campus access switch Keep a fiber-based switching deployment compliant without changing hardware Why This Product 1 Renewal-only license for an installed switch 2 1-year term instead of perpetual coverage 3 Sized for a 12-port fiber Catalyst 3850 4 Cisco DNA Advantage entitlement versus Essentials
