Advanced persistent security threats exponential growth of 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 network fabric that powers 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. These include:

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

The Cisco Catalyst^® 9400 Series switches are Cisco's leading modular enterprise switching access distribution and core platform built for security IoT and cloud. These switches form the foundational building block for SD-Access ? Cisco's lead enterprise architecture. The platform provides unparalleled investment protection with a chassis architecture that is capable of supporting up to 9 Tbps of system bandwidth and unmatched power delivery for high density IEEE 802.3bt (60W and 90W PoE). Redundancy is now table stakes across the portfolio. The Catalyst 9400 delivers state-of-the-art High Availability (HA) with capabilities like Cisco^® StackWise^® Virtual technology with In-service-software-upgrade (ISSU) SSO/NSF uplink resiliency N+1/N+N redundancy for power supplies. The platform is enterprise optimized with an innovative dual-serviceable fan tray design side to side airflow and is closet-friendly with ~16" depth. A single system can scale up to 384 access ports with your choice of 1G copper mGig Cisco UPOE+^© UPOE PoE+ 1G Fiber options. The availability of 1/10 G fiber ports facilitate aggregation of existing small form factor fixed access switches. The addition of the new SUP-1XL-Y supervisor allows unique investment protection through 25 G uplink connectivity option which is becoming a popular alternative to 10 G in the core. The platform also supports advanced routing and infrastructure services SD-Access capabilities and network system virtualization. These features enable optional placement of the platform in the core and aggregation layers of small to medium-sized campus environments.
