1. 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.

2. Key Highlights & Benefits

  • 1 Tbps StackWise-1T Stacking
  • Up to eight switches operate as one with sub-second failover, ensuring always-on services.
  • Line-rate 100 G Hardware IPsec
  • Native encryption accelerates secure WAN or cloud edge tunnels with no performance penalty.
  • 90 W Cisco UPOE+ & 60 W UPOE
  • Powers Wi-Fi 6E access points, smart lighting, and collaboration endpoints over existing cabling.
  • Versatile Uplink Choices (1/10/25/40/100 G)
  • Hot-swappable network modules or fixed 25 G ports protect future bandwidth investments.
  • Meraki Cloud Monitoring & Management
  • “-M” SKUs onboard to Meraki Dashboard with a click for unified, cloud-delivered operations.
  • On-box Application Hosting & ThousandEyes
  • Embedded x86 cores run security gateways, sensors, or custom Docker apps at the edge.
  • StackPower Shared PSUs
  • Pool power supplies across the stack, dynamically reallocating PoE budget and improving redundancy efficiency.
  • Full Automation & Telemetry
  • gNMI, NETCONF/YANG, and model-driven streaming telemetry enable intent-based networking and AIOps integrations.
