C9300-24S-E Description

C9300-24S 
The Cisco Catalyst C9300-24S-E is a premier enterprise-class fiber aggregation switch, designed for security, IoT, and cloud. As part of the Catalyst 9300 Series, it features 24 Gigabit Ethernet SFP ports, making it ideal for aggregating wiring closets or providing secure fiber-to-the-desktop connectivity. Powered by the unified UADP 2.0 ASIC and an x86 CPU, it delivers programmable pipeline capabilities and investment protection through modular uplinks (supporting 10G, 25G, 40G, or 100G) and redundant power configurations.

Running on Cisco IOS XE with the Network Essentials license, this model provides robust Layer 3 routing features, advanced security including Encrypted Traffic Analytics (ETA), and trustworthy systems. With StackWise-480 technology, it offers 480 Gbps of stacking bandwidth, allowing it to form a highly resilient and unified management domain with other Catalyst 9300 switches, ensuring non-stop business continuity for critical network distribution layers.

Key Features

High-Performance Aggregation

Fiber Connectivity. Equipped with 24 SFP ports, this switch serves as a powerful aggregation point for downstream access switches or as a secure fiber connectivity solution for long-distance endpoints, eliminating the distance limitations of copper cabling.

Future-Proof Modular Design

Flexible Uplinks. Unlike fixed-configuration switches, the C9300-24S-E supports swappable network modules. You can deploy 10G uplinks today and migrate to 25G, 40G, or even 100G in the future without replacing the chassis, securing your infrastructure investment.

Mission-Critical Resiliency

StackWise-480. Delivers the industry’s highest backplane stacking bandwidth at 480 Gbps. It supports Stateful Switchover (SSO), ensuring sub-second failover and non-stop forwarding for voice and video traffic if the active member fails.

Advanced Security Architecture

Encrypted Traffic Analytics. Identify malware hidden in encrypted traffic without decrypting it. Combined with AES-128 MACsec encryption and Trustworthy Systems (Secure Boot), it provides a fortified defense against modern cyber threats.

IoT and Mobility Ready

Converged Wired/Wireless. As the foundation for SDA (Software-Defined Access), this switch can handle high-density IoT environments and acts as a fabric edge, simplifying the onboarding and segmentation of devices across the network.

Operational Simplicity

x86 CPU & UADP 2.0. The powerful onboard x86 processor allows for third-party container hosting directly on the switch. Combined with model-driven telemetry, it enables proactive monitoring and automated troubleshooting to reduce OPEX.

Applications Scenarios

Fiber Aggregation Layer

Collapsed Core for Branches. In medium-sized branch offices, the C9300-24S-E acts as a perfect collapsed core switch. It aggregates uplinks from multiple copper access switches (e.g., C9200) via fiber and connects to the WAN router, providing high-speed switching and routing in a single reliable tier.

Secure Fiber-to-the-Desk

High-Security Environments. For government, military, or financial institutions requiring EMI immunity and strict physical layer security, this model delivers direct fiber connectivity to workstations, ensuring data integrity over long distances where copper is susceptible to interference or tapping.

Campus Distribution Hub

Scalable Building Distribution. In a multi-building campus, use this switch to collect fiber links from various floors or departments. Its StackWise-480 capability allows IT to manage the distribution layer of an entire building as a single logical device, simplifying configuration and spanning-tree management.

Selection Guide

  • Select C9300-24S-E for Aggregation
    Choose this model if you need to aggregate multiple access switches via fiber. The 24 SFP ports and StackWise-480 architecture make it a robust distribution switch for medium-sized campuses.
  • Ideal for Modular Flexibility
    Unlike the C9300L fixed series, this model supports swappable uplink modules. This is critical for businesses that plan to upgrade their backbone from 10G to 40G or 100G in the future without replacing the entire switch.
  • Why Network Essentials?
    This license level is perfect for standard enterprise routing needs (OSPF, EIGRP, Static). Unless you require full automated SD-Access segmentation or VXLAN overlay capabilities immediately, Essentials provides the best price-to-performance ratio.
