C9300-24S-A Description
The Cisco Catalyst C9300-24S-A is a premier fiber aggregation switch designed for high-performance campus networks that require advanced routing and flexibility. As the top-tier fiber model in the Catalyst 9300 modular family, it features 24 Gigabit SFP ports for long-distance fiber connectivity and a modular expansion slot that supports high-speed uplinks ranging from 1G to 40G. This makes it an ideal solution for aggregating wiring closets or providing secure, electromagnetic-interference-free connectivity to desktops in sensitive environments.
Equipped with the Network Advantage software license, this switch delivers the most comprehensive feature set in its class, including full enterprise routing (BGP, MPLS), VRF-Lite, and complete SD-Access fabric capabilities. Powered by the UADP 2.0 ASIC and an x86 CPU, it supports programmable networks and container-based application hosting. With StackWise-480 technology, it offers 480 Gbps of stacking bandwidth, providing a highly scalable and resilient foundation for mission-critical distribution layers.

Key Features
Campus Distribution. Designed to serve as a reliable distribution switch for aggregating multiple copper access switches. The 24 SFP ports allow for fiber connections from wiring closets spread across a large building or campus, overcoming the 100-meter distance limitation of copper cabling.
Scalable Bandwidth. Unlike fixed-configuration fiber switches, this model features a modular uplink slot. Organizations can deploy 10G uplinks today and seamlessly upgrade to 25G or 40G in the future as traffic demands grow, protecting their initial hardware investment.
Unified Management. Supports stacking of up to 8 units with 480 Gbps of backplane throughput. This capability allows network engineers to manage an entire aggregation block as a single logical device, providing stateful switchover (SSO) redundancy and simplifying configuration updates.
Full Core Capabilities. Includes the top-tier Network Advantage license, enabling advanced protocols like BGP, MPLS, and VRF-Lite. This allows the switch to perform complex core routing functions, handle WAN peering, and provide secure network segmentation without needing a dedicated router.
Automated Network Fabric. Fully capable of acting as a Fabric Edge or Control Plane node in Cisco’s SD-Access architecture. It supports VXLAN encapsulation and LISP, enabling automated user mobility, identity-based security policies, and macro-segmentation across the campus.
Physical Layer Security. For high-security environments like government or defense, fiber connectivity prevents electromagnetic emanations and makes physical tapping extremely difficult. This switch provides a secure, high-speed fiber connection directly to user workstations.
Application Scenarios
Collapsed Core. For medium-sized enterprise campuses, this switch acts as the central hub. It aggregates Gigabit fiber links from access switches on different floors and routes traffic to the data center or WAN using its advanced BGP/OSPF capabilities and high-speed uplinks.
Fiber-to-the-Desk. Ideal for SCIFs (Sensitive Compartmented Information Facilities) or financial trading floors where data integrity is paramount. Connecting workstations via fiber eliminates EMI interference and provides a higher level of physical security than copper Ethernet.
Long-Distance Reach. Perfect for manufacturing plants or large warehouses where endpoints are located far apart. The fiber ports allow the switch to connect devices located hundreds of meters or even kilometers away, which is impossible with standard copper switches.

Selection Guide
- Engineering Requirement for Modular Uplinks
Choose this modular C9300 model if you anticipate bandwidth growth. The ability to swap network modules allows you to upgrade uplinks from 1G to 40G without replacing the switch, securing your investment for the long term. - Requirement for Full Core Routing
Select this Advantage (-A) model if the switch needs to act as a core or distribution node running BGP, MPLS, or complex VRF segmentation. The Essentials (-E) model lacks these advanced protocols and is limited to basic access functions. - High-Density Fiber Aggregation
This model is the specific choice when you need to aggregate 24 fiber links from downstream switches or connect workstations over long distances. If you only need copper ports, the C9300-24T-A is the correct alternative. - SD-Access Fabric Deployment
If you are building a Cisco DNA Center SD-Access network, this Advantage model is required to perform advanced fabric roles (Control Plane/Border Node). The Essentials model is limited to acting only as a basic Fabric Edge node.
