Cisco C9500-24X-A Enterprise Aggregation Switch
The Cisco Catalyst 9500-24X-A is a 1 RU fixed-core enterprise aggregation switch optimized for U.S. campus and data-center deployments—from Silicon Valley innovation campuses to Wall Street trading floors.
It delivers 16 auto-sensing 10 Gbps SFP+ downlink ports plus one C9500-NM-8X network module slot (8×10 Gbps SFP+ included), all powered by a multicore x86 CPU and Cisco’s UADP ASIC for security, IoT, and cloud-scale performance.
Running Cisco IOS XE with the Network Advantage license, it supports advanced Layer 2/3 services, Programmable Pipeline extensibility, and deep buffer capacity—while maintaining seamless integration via Cisco Catalyst Center or Meraki cloud monitoring.
