Product Overview

The Cisco Catalyst C9300X-12Y is a high-performance enterprise access and aggregation switch designed for bandwidth-intensive campus environments. It provides native 25 GbE connectivity at the access layer, combined with integrated 100 GbE uplinks for high-speed aggregation into distribution or core networks. Built on the Catalyst 9300X platform, this model delivers significantly higher throughput than standard access switches, supporting advanced Layer 2 and Layer 3 forwarding in hardware. The C9300X-12Y enables organisations to support modern workloads, high-density wireless, and compute-driven traffic while maintaining a compact access-layer footprint.

Ideal Deployment / Environment:
The C9300X-12Y is suited to enterprise campus access and aggregation layers supporting high-performance endpoints, server-attached access, and next-generation wireless deployments. It fits environments requiring 25 GbE access speeds with direct 100 GbE uplinks into aggregation or core layers, such as large campuses, research facilities, and distributed enterprise sites. The platform supports scalable designs that demand high throughput, low latency, and long-term network growth.
