Cisco C9200L-STACK
Cisco Catalyst 9200L Stack Module
Product Highlights
Managing a growing fleet of standalone access-layer switches creates operational overhead — inconsistent configurations, complex troubleshooting, and limited resiliency. The Cisco C9200L-STACK Catalyst 9200L Stack Module eliminates these challenges by enabling Cisco StackWise-80 technology across your Catalyst 9200L fixed-uplink switches.
With 80 Gbps of stacking bandwidth, the C9200L-STACK module connects up to eight Catalyst 9200L switches into a single logical unit with a unified control plane and management interface. Administrators can configure, monitor, and troubleshoot the entire stack from a single IP address, dramatically reducing operational complexity. The stack delivers seamless failover and non-stop forwarding, ensuring high availability for mission-critical branch and campus networks.
The C9200L-STACK is a compact plug-in module that installs into the rear stacking port of any C9200L switch. It is designed exclusively for Catalyst 9200L fixed-uplink models and cannot be mixed with modular C9200 SKUs or other Catalyst series. Whether you are deploying a new branch office or expanding an existing enterprise access layer, the C9200L-STACK provides the scalability, resiliency, and simplified management that modern networks demand.
Features & Benefits
StackWise-80 Technology
Cisco StackWise-80 delivers 80 Gbps of full-duplex stacking bandwidth, creating a high-speed fabric between member switches. This ensures low-latency data-plane synchronization and control-plane convergence, keeping your network responsive even under heavy load.
Unified Stack Management
Stack up to eight Catalyst 9200L switches and manage them as a single logical entity through one IP address. Configuration changes, firmware upgrades, and monitoring tasks apply across the entire stack, reducing administrative effort and minimizing human error.
High Availability & Resiliency
The ring-based stacking topology provides seamless failover — if a member switch or link fails, traffic is automatically rerouted across the remaining stack fabric. Non-stop forwarding ensures continuous operation and minimal disruption to end users.
Plug-in, Field-Replaceable Design
The C9200L-STACK module installs directly into the rear stacking slot of any Catalyst 9200L switch. Its compact, field-replaceable form factor allows IT teams to add stacking capability on demand without replacing the switch or scheduling extended downtime.
Flexible Cable Options
A 0.5 m Type-3 data-stack cable is included by default when purchased as part of the stack kit. Optional 1 m and 3 m cables (STACK-T4-1M, STACK-T4-3M) are available separately, enabling stacking across adjacent racks or within larger wiring closets.
Deployment Scenarios
Branch Office Access Layer
Deploy two to four Catalyst 9200L switches in a branch office and stack them with the C9200L-STACK module. The unified management plane reduces the need for on-site IT expertise, while StackWise-80 resiliency ensures uninterrupted connectivity for branch users.
Enterprise Campus Access Aggregation
Stack up to eight C9200L switches across one or two racks in a campus IDF closet. The 80 Gbps fabric supports high-density access for endpoints and Wi-Fi access points, while single-pane management simplifies day-to-day operations for the campus network team.
Retail and Distributed Sites
Standardize on Catalyst 9200L stacks across dozens of retail locations. The C9200L-STACK module enables consistent, template-driven configurations pushed to each site, reducing deployment time and ensuring uniform security and QoS policies.

Compatibility Notes
Compatible Platforms:
- All Cisco Catalyst 9200L fixed-uplink switch models (C9200L SKUs)
Not Compatible With:
- Cisco Catalyst 9200 modular-uplink models (C9200 SKUs) — these require the C9200-STACK-KIT with StackWise-160
- Cisco Catalyst 9200CX compact models — stacking is not supported
- Cisco Catalyst 2960-X, 2960-XR, C9300, C9300L, or any other Catalyst series
Important: Mixed stacking between C9200L and C9200 modular models is not supported due to different stacking bandwidth architectures. All members in a stack must be C9200L SKUs.
