Cisco C9500-24Q-E Full Official English Product Description
Product Overview
The Cisco Catalyst C9500-24Q-E is a high-density 1RU fixed core & aggregation switch preloaded with Network Essentials perpetual license, belonging to Cisco flagship Catalyst 9500 enterprise switching family. Powered by UADP 2.0 ASIC, multi-core x86 CPU and Cisco IOS XE operating system, it delivers wire-speed high-density 40G QSFP+ fiber ports, solid Layer 2/Layer 3 forwarding, foundational hardware security and StackWise-480 stacking technology. It is a cost-effective high-bandwidth aggregation solution for mid-size campus, small-to-medium data center leaf-spine fabrics and inter-building fiber backbone deployments for networks with basic routing, security and automation requirements.
