The Cisco Catalyst 9500 Series Switch, Model C9500-24Y4C-E, is an enterprise-class, fixed-configuration core and aggregation switch engineered specifically for high-performance corporate campus backbones, high-density distribution layers, and next-generation data center interconnects. Purpose-built to handle massive traffic volumes and high-bandwidth applications, this 1-Rack Unit (1RU) platform features (24) 1/10/25-Gigabit SFP28 optical ports and (4) high-speed 40/100-Gigabit QSFP28 uplink ports, providing ultra-low latency and scalable fiber connectivity.
Powered by Cisco's advanced Unified Access Data Plane 3.0 (UADP 3.0) ASIC architecture paired with an x86 multi-core processor, 16 GB of DRAM, and 16 GB of Flash memory, the C9500-24Y4C-E delivers non-blocking switching throughput up to 2.0 Tbps with a forwarding rate of 1.6 Bpps (Billion packets per second). Running the open, programmable Cisco IOS XE operating system, it supports full enterprise Layer 3 features (including OSPF, EIGRP, BGP, IS-IS, and VRF), advanced Quality of Service (QoS), and hardware-based MACsec 256-bit encryption readiness. Bundled with the Network Essentials feature set and a 3-Year Cisco DNA Essentials license, it enables automated management, network analytics, and zero-touch provisioning via Cisco Catalyst Center (formerly Cisco DNA Center).
