C9300-48UN-E Overview

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. The Catalyst 9300 Series switches form the foundational building block for Software-Defined Access
(SD-Access), Cisco’s lead enterprise architecture. At 480 Gbps, 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 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 Cisco Universal Power Over Ethernet (Cisco UPOE®) and Power over Ethernet Plus (PoE+) ports. The switches are based on the Cisco Unified Access™ Data Plane 2.0 (UADP) 2.0 architecture which not only protects your investment but also allows a larger scale and higher throughput. 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 DNAâ„¢) with 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.

Frequently Asked Questions

What are the primary performance capabilities of the C9300-48UN-E switch? +
The Cisco Catalyst C9300-48UN-E is a high-performance, stackable access switch designed to handle modern high-bandwidth requirements. It features 48 ports supporting mGig speeds up to 5Gbps, making it an ideal choice for high-speed Wi-Fi 6 access points and bandwidth-intensive enterprise endpoints that exceed standard Gigabit Ethernet throughput.
Does the C9300-48UN-E include advanced Layer 3 routing functionality? +
This model comes with the Network Essentials license, which provides foundational Layer 3 routing capabilities, including static routing, RIP, and OSPF. It is optimized for versatile deployment as both a sophisticated Layer 2 access switch and a capable Layer 3 edge switch, fitting seamlessly into diverse enterprise network architectures that require robust segmentation and connectivity.
Can the C9300-48UN-E be stacked with other Catalyst 9300 series switches? +
Yes, this switch supports Cisco StackWise technology, allowing you to combine multiple units into a single logical entity. This simplifies management and increases port density while providing high availability through sub-50-millisecond failover. Stacking provides a unified control plane, enabling efficient resource allocation across your stack to support growing campus network demands.
What type of power features does the C9300-48UN-E offer for connected devices? +
This switch is built for high-density PoE environments. It provides reliable Power over Ethernet capabilities to power advanced enterprise peripherals like IP cameras, VoIP phones, and wireless access points. By delivering consistent power across its 48 ports, it eliminates the need for individual power injectors, thereby reducing cable clutter and simplifying the deployment of power-hungry IoT infrastructure.
Is the Network Essentials license upgradeable on the C9300-48UN-E? +
The C9300-48UN-E ships with the Network Essentials license, which is designed to cover standard enterprise connectivity and routing needs. While this license provides a comprehensive feature set for most campus access environments, Cisco allows for future upgrades to Network Advantage if your organization's requirements evolve to include advanced automation, telemetry, or more complex routing protocols.
