What Is the Cisco Catalyst C9300-24S-E?
The Cisco Catalyst C9300-24S-E is a 24-port Layer 3 switch optimized for fiber-based network architectures. Part of the Catalyst 9300 Series, it features 24x 1G/10G SFP+ ports and 4x additional 10G SFP+ uplinks, making it ideal for high-speed aggregation and backbone deployments. The “E” designation indicates it includes the Cisco DNA Essentials license, enabling foundational automation, security, and SD-Access capabilities.
Key Technical Features
- Port Configuration: 24x 1G/10G SFP+ ports + 4x 10G SFP+ uplinks for flexible connectivity.
- Stacking: Supports StackWise-320, delivering up to 320 Gbps stacking bandwidth across 8 units.
- Performance: Forwarding rate of 300 Mpps and 480 Gbps switching capacity for low-latency traffic handling.
- Software: Runs Cisco IOS XE with DNA Essentials for centralized management via Cisco DNA Center.
- Security: Includes Cisco TrustSec, MACsec encryption, and role-based access control (RBAC).
Primary Use Cases
- Data Center Edge: Connects servers and storage with high-speed 10G fiber links.
- Campus Core: Aggregates traffic from access switches in large enterprises or universities.
- Service Provider Access: Supports Metro Ethernet or fiber-to-the-business (FTTB) deployments.
- High-Density 10G Workloads: Ideal for environments like video production studios or research labs.

Deployment Considerations
The C9300-24S-E shines in environments where fiber density and 10G throughput are non-negotiable. In practice, its lack of PoE limits it to aggregation roles, but this also reduces power consumption and cooling needs. When deploying, pair it with PoE access switches (e.g., C9300-24P-E) for a balanced architecture. One caveat: the 10G uplinks can become bottlenecks in hyper-scale scenarios—plan for 40G/100G upgrades in the core. Always validate SFP+ module compatibility to avoid link negotiation issues.
