Built for security, IoT, mobility, and cloud
The Cisco® Catalyst® 9300 Series switches are Cisco’s lead stackable enterprise switching platform built for security, IoT, mobility, and cloud. They are 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. At up to 1TB, they are the industry’s highest-density stacking bandwidth solution with the most flexible uplink architecture. The Catalyst 9300 Series is the first optimized platform for high-density Wi-Fi 6 and 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.
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 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 not only protects your investment but also allows a 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.
The Foundation of Software-Defined access
Advanced persistent security threats. The exponential growth of Internet of Things (IoT) devices. Mobility everywhere. Cloud adoption. All of these 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 the rollout of business services.
The Cisco Digital Network Architecture (Cisco DNA) with Software-Defined Access (SD-Access) is the network fabric that powers business. It 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
Cisco DNA software
Cisco DNA Software offers a valuable and flexible way to buy software for the access, WAN, and data center domains. At each stage in the product lifecycle, Cisco DNA Software helps make buying, managing, and upgrading your network and infrastructure software easier. Cisco DNA Software provides:
- Flexible licensing models to smoothly distribute customers’ software spending over time
- Investment protection for software purchases through software services–enabled license portability
- Access to updates, upgrades, and new technology from Cisco through Cisco®Software Support Services (SWSS)
- Lower cost of entry with the new Cisco DNA Subscription for Switching model
- Access to end-to-end service assurance through Cisco ThousandEyes* Network and Application Synthetics (included with Cisco DNA Advantage and Premier licenses)
Cisco DNA lets you manage your entire switching structure as a single, converged component. With one management system and one policy for wired and wireless networks, it offers an efficient way to provide more secure access.
* Each Catalyst 9300 or 9400 Cisco DNA Advantage or Premier subscription entitles the customer to run the equivalent of one ThousandEyes network or web test every 5 mins from a ThousandEyes enterprise agent (22 units per month), up to a maximum of 110,000 units per month of ThousandEyes test capacity per customer. ThousandEyes Cloud Agent access is not included in the Cisco DNA license entitlement. Test capacity can be increased and Cloud Agents accessed with purchase of additional ThousandEyes Network and Application Synthetics.
