Enable high-performance switch stacking for your Catalyst 9300L network — the Cisco C9300L-STACK-KIT= delivers high-bandwidth StackWise-320 connectivity, simplified management, and resilient access layer scaling
Model Type: Stack Kit Accessory
Category: Cisco Catalyst 9300L Switch Stacking Hardware
Overview
The Cisco C9300L-STACK-KIT= is a stacking kit designed to enable StackWise-320 stacking for Cisco Catalyst 9300L Series switches. It allows multiple physical switches to be connected into a single logical unit, simplifying management, increasing resiliency, and enabling higher aggregated throughput across the stack.
This stacking kit is essential when building scalable access layers in enterprise or campus networks using Cisco Catalyst 9300L switches.
Key Features
• StackWise-320 Support — Enables high-speed interconnection between switches with up to 320 Gbps of stacking bandwidth using Cisco’s StackWise technology.
• Supports Up to 8 Switches — Allows stacking of up to eight Catalyst 9300L switches as a single logical chassis for streamlined management and redundancy.
• Includes Stack Modules & Cable — The kit typically includes two stack adapters and one external stacking cable (about 0.5 m).
• Plug-In Modular Design — Stack adapters install into the dedicated stacking slots on each switch, and the stacking cable physically links them for data and control traffic.
• Simplified Management & Resiliency — Switches in a stack operate under a single management plane, with automatic failover and redundancy should a stack member fail, reducing operational complexity.
• Designed for C9300L Models — Compatible specifically with Cisco Catalyst 9300L fixed-uplink switches (requires matching stack kit version across all units in the stack).
