Managed L2/L3 switch Cisco Catalyst C9300L-48UXG-4X-E

The Cisco Catalyst C9300L-48UXG-4X-E is a managed L2/L3 enterprise switch designed for secure, high-performance access and aggregation. It provides 48 10G Ethernet ports, a switching capacity of 392 Gbit/s and a MAC address table of 32,000 entries. The switch supports Power over Ethernet (PoE) and a wide range of IEEE networking standards, and is built on the Catalyst 9300 family platform that enables Software-Defined Access (SD-Access), high-density Wi‑Fi 6 deployments, and hosting of containerized or third-party applications on the device.

Advantages

The switch delivers high-density 10G connectivity with a compact managed L2/L3 feature set and Cisco IOS XE programmability. It supports resilient stacking and power sharing, advanced security and segmentation through Cisco DNA and SD-Access, and hardware crypto acceleration on Catalyst 9300X-class ASICs. Built-in support for PoE and industry networking standards ensures compatibility with common enterprise endpoints and infrastructure.

Suitable for

• High-performance access layer in enterprise or campus networks
• Dense 10G connectivity for aggregation or server access
• Environments requiring PoE for phones, cameras, or wireless access points
• Networks using Cisco DNA / SD-Access for unified wired and wireless policy

How to use

Install the switch in a standard 19-inch rack and connect power and uplink links according to your site design. Use the Cisco IOS XE management interface, Cisco DNA Center or CLI to configure L2/L3 features, VLANs, routing, QoS and PoE settings. For stacked deployments, configure StackWise stacking to enable unified management and stateful switchover. Apply SD-Access policies and Cisco DNA licensing where required to enable group-based policies, network segmentation and unified wired/wireless management.

Recommendations

Use this model in enterprise access or aggregation roles where high-density 10G ports and PoE support are required; pair it with Cisco DNA subscriptions and compatible Catalyst 9300 family devices to enable full SD-Access features, hardware crypto acceleration, and resilient stacking.
