Built for security, IoT, mobility, and cloud, the Cisco Catalyst 9300 Series switches are Cisco’s lead stackable enterprise switching platform. They represent the next generation of the industry’s most widely deployed switching platform. Catalyst 9300 Series switches form the foundational building block for Software-Defined Access (SD-Access), Cisco’s lead enterprise architecture. With up to 1TB, they offer the industry’s highest-density stacking bandwidth solution and the most flexible uplink architecture. The Catalyst 9300 Series is the first optimized platform for high-density Wi-Fi 6 and 802.11ac Wave 2, setting new maximums for network scale. These switches are future-ready, featuring an x86 CPU architecture and increased memory, enabling them to host containers and run third-party applications and scripts natively.

The Catalyst 9300 Series is designed for Cisco StackWise technology, providing flexible deployment with support for nonstop forwarding with Stateful Switchover (NSF/SSO), ensuring the most resilient architecture in a stackable solution. The highly resilient and efficient power architecture features Cisco StackPower, delivering high-density Power over Ethernet Plus (PoE+), 60W Cisco Universal Power over Ethernet (Cisco UPOE), and 90W Cisco UPOE+ ports. The switches are based on the Cisco Unified Access Data Plane 2.0 (UADP) architecture, which protects your investment while allowing for larger scale and higher throughput. Catalyst 9300X models are based on a new ASIC, UADP 2.5sec, which adds Crypto support in hardware, including IPSEC. A modern operating system, Cisco IOS XE with programmability, offers advanced security capabilities and Internet of Things (IoT) convergence.
