Cisco Catalyst 9400 Switches

The Cisco Catalyst^® 9400 Series is Cisco's leading modular enterprise switching access and aggregation platform and is built for security the Internet of Things (IoT) and multicloud environments. These switches form the foundational building blocks for Cisco^® SD-Access our leading enterprise architecture. The platform provides strong investment protection with a chassis architecture that is capable of supporting up to nine Tbps of system bandwidth and industry-leading power delivery for high-density IEEE 802.3bt (60 W and 90W PoE). Redundancy is now available across the portfolio. Cisco Catalyst 9400 Series switches deliver state-of-the-art high availability with capabilities such as Nonstop Forwarding and Stateful Switchover (NSF/SSO) In-Service Software Upgrade (ISSU) uplink resiliency and N+1/N+N redundancy for power supplies and Cisco StackWise^® virtual (SVL) with ISSU. The platform is enterprise-optimized with an innovative dual-serviceable fan-tray design and side-to-side airflow and is closet-friendly with approximately 16 inches in depth. A single system can scale up to 384 access ports with your choice of 1 Gigabit Ethernet copper 1 Gigabit Ethernet fiber Cisco UPOE+^© Cisco Universal Power over Ethernet (Cisco UPOE^®) and Power over Ethernet Plus (PoE+) options and up to 192 ports of 10G fiber and multigigabit options. The platform also supports advanced routing and infrastructure services SD-Access capabilities and network system virtualization. These features enable placement of the platform in the core and aggregation layers of small- to medium-sized campus environments.

A foundation for Software-Defined Architecture

Advanced persistent security threats the exponential growth of the Internet of Things (IoT) devices mobility everywhere and cloud adoption require a network fabric that integrates advanced hardware and software innovations to automate secure and simplify customer networks. The goal of this network fabric is to enable customer revenue growth by accelerating business service rollout.

The Cisco^® Digital Network Architecture (Cisco DNA) with Software-Defined Access (SD-Access) is the most advanced network fabric to power customer business. Cisco DNA is an open and extensible software-driven architecture that accelerates and simplifies your enterprise network operations. The programmable architecture frees your IT staff from time consuming repetitive network configuration tasks so they can focus instead on innovation that positively transforms your business. SD-Access enables policy-based automation from edge to cloud with foundational capabilities that include:

• Simplified device deployment
• Unified management of wired and wireless networks
• Network virtualization and segmentation
• Group-based policies
• Context-based analytics

Cisco Catalyst 9400 Series switches support enterprise fabric to provide these benefits while extending controller-based networking with uniform enterprise-wide policy and mobility.
