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.
What is the primary use case for 5Gbps multi-gigabit ports on this switch? +
The 5Gbps multi-gigabit ports are specifically engineered to support the higher throughput demands of modern Wi-Fi 6 and Wi-Fi 6E wireless access points. By utilizing existing Cat6a or better cabling, these ports remove the bottleneck typically found in standard 1Gbps switches, ensuring that your wireless users experience the full speed potential of your high-density wireless network infrastructure.
How do I manage the C9300-48UN-E within my enterprise network? +
You can manage this switch using standard Cisco command-line interface (CLI) or via Cisco DNA Center for advanced intent-based networking. It supports modern management protocols and centralized configuration tools, which streamline provisioning and ongoing monitoring. This flexibility allows IT teams to choose the management style that best fits their existing operational workflows and visibility requirements.
Is the C9300-48UN-E suitable for high-density campus deployments? +
Absolutely. With its 48-port density and stackable architecture, this switch is designed to serve as the backbone of modern office access layers. Its ability to provide multi-gigabit speeds and efficient PoE delivery makes it perfect for environments where high-performance connectivity is required for a large number of wired and wireless devices, ensuring consistent reliability across the entire campus.
