Core Functionality of the C9500-24X-E
The C9500-24X-E is a Cisco Catalyst 9500 Series fixed-configuration switch built for high-speed enterprise core and aggregation layers. It features 24x 10G/25G SFP28 ports and 4x 40G/100G QSFP28 uplinks, making it ideal for environments demanding dense connectivity and low-latency performance.
Technical Specifications & Performance
- Port Density: 24x 25G ports (configurable as 10G via SFP+ modules) + 4x 100G uplinks.
- Throughput: 1.44 Tbps switching capacity with 960 Mpps forwarding rate.
- Stacking: Supports Cisco StackWise-1T, enabling up to 8 switches to operate as a single logical unit.
- Software: Runs Cisco IOS XE with DNA Essentials for automated policy enforcement and threat response.
- Power Efficiency: Energywise 3.0 compliance reduces power consumption by 20–35% compared to predecessors.
Target Use Cases
This switch is optimized for:
- Data Center Interconnects: Seamlessly links server farms with 100G spine-leaf topologies.
- High-Frequency Trading: Delivers sub-3μs latency for algorithmic trading platforms.
- Media Production Networks: Handles uncompressed 4K/8K video streams with Jumbo Frame support (9K MTU).

Addressing Common Deployment Questions
Q: Can existing 1G devices connect to the 25G ports?
A: Yes, using 10G/1G SFP+ transceivers (sold separately) for backward compatibility.
Q: Does it support MACsec encryption?
A: Yes—256-bit MACsec is hardware-accelerated on all ports.
Q: What’s the maximum PoE budget?
A: Not applicable—this model is designed for non-PoE core roles.
