Cisco C9500X-60L4D-E Full English Product Description

Product Overview

The Cisco Catalyst C9500X-60L4D-E is a high-density 1RU next-generation core/aggregation switch preloaded with Network Essentials perpetual license, belonging to the advanced Catalyst 9500X portfolio powered by Cisco Silicon One Q200 7nm programmable P4 ASICCisco. Built for large enterprise campus aggregation and medium-to-large data center leaf-spine fabrics, this model delivers massive 10/25/50G SFP56 downlink density paired with 400G QSFP-DD ultra-high-speed uplinks. It balances cost efficiency, line-rate Layer 2/3 forwarding, foundational hardware security, and robust high availability for networks requiring core-scale performance without full advanced routing & SD-Access premium feature sets.
