Built to reimage connection, reinforce security, and redefine experience Cisco Catalyst™ 9300 Series Switches are Cisco’s lead stackable enterprise access switching platform and, as part of the Catalyst 9000 family, are built to transform your network to handle a hybrid world where the workplace is anywhere, endpoints could be anything, and applications are hosted all over the place. The Catalyst 9300 Series, including the Catalyst 9300X models, continues to shape the future with continued innovation that helps you reimagine connections, reinforce security and redefine the experience for your hybrid workforce, big or small. With Catalyst 9300 Series switches, you choose how you want to manage your network – on-premises, virtual, or from the cloud. The many industry firsts of the Catalyst 9300 Series include: • Up to 1 TB of stacking bandwidth: With Cisco StackWise-1T, Catalyst 9300 Series switches are the industry’s highest-density stacking bandwidth solution with the most flexible uplink architecture. • Flexible and dense uplink offerings with 100 Gigabit Ethernet (G), 40G, 25G, Multigigabit, 10G, and 1G modular uplinks. • Mixed stacking with backward compatibility: Stack your Catalyst 9300X fiber switches with Catalyst 9300 and Catalyst 9300X Multigigabit switches, bringing stackable high-speed fiber to the access layer. • Highest number of Multigigabit ports: With standalone and StackWise-1T, Catalyst 9300X models enable 48 Multigigabit ports in standalone mode and 448 Multigigabit ports with an 8-member stack. • Highest 90W UPOE+ density: Enable your OT/IT needs with up to 48 ports of 90W Cisco UPOE+ in standalone mode or 384 ports of 90W UPOE+ with an 8-member stack. • StackPower with backward compatibility: Enable power resiliency with higher power budgets in a mixed Catalyst 9300 and Catalyst 9300X stack. • 100G IPsec in hardware: Built on the Cisco® Unified Access Data Plane (UADP) 2.0sec application-specific integrated circuit (ASIC), the Catalyst 9300X models come with 100G line-rate IPsec to enable various options for new edge connectivity. • Secure tunnel connectivity: With the new edge, the Catalyst 9300X enables secure connections to secure internet gateways, cloud service providers, and site-to-site connectivity using IPsec tunnels with 256-bit Advanced Encryption Standard encryption (AES-256) and speeds up to 100G. • Enhanced application hosting: With twice the capacity and additional RAM, Intel® QuickAssist Technology (QAT), and 2x 10G AppGig ports, the Catalyst 9300X models can host multiple Cisco Signed performance-savvy applications. • ThousandEyes enabled: Enable end-to-end visualization of the path from campus/branch to clouds/data center with Cisco ThousandEyes® Network and Application Synthetics (included with Cisco DNA Advantage licenses). • Cisco ASAc firewall enabled: Using application hosting, Cisco Adaptive Security Virtual Appliance (ASAc) and stateful inspection of traffic can be seamlessly added to existing networks without any additional hardware.
