​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.

​C9300-24S-E vs. C9300-24P-E: Critical Differences​

​Port Type​ 24x SFP+ (fiber) 24x RJ45 (PoE+)
​PoE Support​ None 370W PoE+ budget
​Uplink Speed​ 10G SFP+ 10G SFP+
​Typical Deployment​ Fiber aggregation/core PoE-driven access layer

​Where to Source the C9300-24S-E Reliably?​

For organizations prioritizing ​​verified Cisco hardware​​ and ​​cost efficiency​​, [​​C9300-24S-E​​ link to (https://itmall.sale/product-category/cisco/) offers certified refurbished or new units with valid DNA Essentials licenses. Itmall.sale ensures full compliance with Cisco’s software and warranty policies, critical for maintaining network integrity.


​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.
