The Catalyst 9300 Series is designed for Cisco StackWise technology, providing flexible deployment with support for nonstop forwarding with stateful switchover (NSF/SSO), for the most resilient architecture in a stackable (sub-50-ms) solution.

The highly resilient and efficient power architecture features Cisco StackPower, which delivers high-density Cisco Universal Power Over Ethernet (Cisco UPOE) and Power over Ethernet Plus (PoE+) ports.

The switches are based on the Cisco Unified Access Data Plane 2.0 (UADP) 2.0 architecture which not only protects your investment but also allows a larger scale and higher throughput. A modern operating system, open Cisco IOS XE with programmability offers advanced security capabilities and Internet of Things (IoT) convergence.

The Catalyst 9300 Series is the first optimized platform for high-density 802.11ac Wave2.
It sets new maximums for network scale.
These switches are also ready for the future, with an x86 CPU architecture and more memory, enabling them to host containers and run third-party applications and scripts natively within the switch.
