Technical Overview of the C9300X-24Y-E
The Cisco Catalyst C9300X-24Y-E is a 24-port 25G Layer 3 switch designed for high-performance enterprise core and data center networks. It features 24 x 25G SFP28 ports and 4 x 40G/100G QSFP28 uplink slots, providing 1.6 Tbps switching capacity for bandwidth-intensive workloads. Bundled with Cisco DNA Essentials licensing (E), it offers foundational automation, security, and analytics tools tailored for scalable deployments.
Key Features and Competitive Advantages
- High-Density 25G Connectivity: Supports AI/ML clusters, NVMe storage, and high-frequency applications with ultra-low latency (sub-3 microseconds).
- Modular Scalability: The QSFP28 uplinks enable flexible configurations, including 4x25G breakout or 100G spine-leaf topologies, future-proofing network investments.
- Advanced Security: Integrates MACsec encryption (AES-256) for data integrity and Cisco TrustSec for policy-based segmentation.
- Energy Efficiency: Utilizes Cisco’s UADP 3.0 ASIC for optimized power consumption, reducing operational costs in 24/7 environments.
Ideal Deployment Scenarios
- Enterprise Core Networks: Aggregates traffic from access switches with BGP/OSPF routing for seamless interdepartmental communication.
- Hybrid Cloud Gateways: Connects on-premises infrastructure to AWS, Azure, or Google Cloud via high-speed uplinks.
- Financial Trading Platforms: Delivers microsecond-level latency for algorithmic trading systems and real-time analytics.

Addressing Critical User Questions
Q: Can the DNA Essentials license be upgraded post-purchase?
A: Yes—Cisco allows migration to DNA Advantage or Premier tiers for advanced features like SD-Access or Cisco Stealthwatch.
Q: Are the 25G ports compatible with 10G transceivers?
A: Yes, SFP28 ports support 10G/25G optics, but ensure Cisco-certified modules for warranty compliance.
Q: Does this switch support VXLAN for network segmentation?
A: Yes, it enables VXLAN-based overlays for multi-tenant or cloud environments.
Q: What redundancy options are available?
A: Supports StackWise Virtual for multi-chassis redundancy and hot-swappable power supplies (optional).
Strategic Perspective
The C9300X-24Y-E is a high-stakes investment for enterprises prioritizing raw throughput and scalability over PoE functionality. Its 25G/100G density makes it ideal for data center spines or financial hubs, but organizations must weigh the lack of PoE against operational needs. For instance, while it excels in pure data roles, campuses requiring UPOE+ should consider the C9300X-24HX-EDU. That said, its DNA Essentials suite provides a cost-effective entry point for automation, making it a pragmatic choice for mid-sized enterprises eyeing gradual cloud transitions. In my experience, deploying this switch in latency-sensitive environments—like trading floors—yields measurable ROI, but thorough needs analysis is crucial to avoid underutilization.
