Cisco Catalyst 9300 Datasheet for Sales & Customers

Positioning & Overview

The Cisco Catalyst 9300 Series is Cisco’s flagship stackable switching platform for modern enterprise access networks. Designed for high-density campus and branch deployments, it delivers secure, automated, and cloud-ready connectivity from 1 GbE up to multigigabit 25 GbE. Powered by Cisco’s latest UADP ASICs, the 9300 Series embeds hardware-based segmentation, real-time telemetry, and application hosting—making it the foundation of Cisco SD-Access, zero-touch provisioning, and experience-first networking.

The family is divided into four lines to match different performance and budget requirements:

Catalyst 9300X – 100 Gbps modular uplinks, 1 Tbps StackWise-1T, and built-in 100 G hardware IPsec.
Catalyst 9300 – Flexible modular uplinks up to 40 Gbps/25 Gbps for mainstream campus access.
Catalyst 9300L – Fixed 1/10/40 Gbps uplinks for cost-optimized Layer 3 access.
Catalyst 9300LM – Compact form factor with fixed 25 Gbps uplinks—ideal for space-constrained or high-density Wi-Fi 6/6E environments.

Frequently Asked Questions (FAQ)

No, the Catalyst 9300 Series uses StackWise-480 technology, which is not compatible with the StackWise-480 or StackWise-160 modules of the Catalyst 3850 Series. Stacking must be performed within the same Catalyst 9300 model family.

The Catalyst 9300 supports standard PoE (up to 30W per port), UPoE (up to 60W per port), and UPoE+ (up to 90W per port, on supported models). Actual power availability depends on the model and installed power supplies.

The maximum stacking bandwidth is up to 480 Gbps when using the StackWise-480 technology, allowing up to 8 switches to operate as a single logical unit for simplified management and increased redundancy.

The official datasheet can be downloaded directly from the Cisco website or via our product page’s “Resources” section.

The Catalyst 9300 Series supports Cisco DNA software licenses (Essentials, Advantage, Premier). Advanced features such as SD-Access, automation, and advanced security require at least the Advantage license level.
