About the Cisco Catalyst 9350 Series Switch 48-port
The Cisco Catalyst 9350 Series 48-port Switch represents a significant advancement in campus access layer architecture, purpose-built for the demanding requirements of enterprise edge environments in 2025 and beyond. Built on Cisco's enhanced UADP (Unified Access Data Plane) ASIC, the 9350 delivers full hardware-based enforcement of security policies, encrypted traffic analytics, and MACsec encryption at line rate across all ports — capabilities that earlier generations handled partially in software. The platform supports both copper PoE+ and multi-gigabit access ports, accommodating the growing density of high-bandwidth Wi-Fi 7 access points, IP surveillance cameras, and IoT endpoints without forwarding bottlenecks.
Ideal for
- High-density enterprise campus access deployments supporting Wi-Fi 7 access points requiring 2.5G or 5G multi-gigabit edge connections per port
- Zero-trust network access enforcement at the campus edge using hardware-accelerated 802.1X, TrustSec SGT tagging, and MACsec line-rate encryption
- Large open-plan office and conference facility networks requiring PoE++ budget for advanced IP phones, video conferencing endpoints, and smart building IoT devices
- SD-Access fabric edge node deployments within Cisco Catalyst Center-managed intent-based networking architectures requiring automated policy lifecycle management
- Healthcare and financial campus environments demanding continuous encrypted traffic analytics and compliance-grade network segmentation without dedicated security appliances
- Scalable multi-building campus stacking scenarios leveraging StackWise-480 for unified management, sub-second redundancy, and simplified software lifecycle operations
