Core Functionality and Compatibility
The Cisco C9200-NM-2Y= is a dual-port 10/25G network module designed for Catalyst 9200 series switches, providing scalable uplink connectivity for high-bandwidth enterprise networks. This module supports SFP-10/25G interfaces, enabling seamless integration with existing fiber or copper infrastructures.
Key features include:
- Two-port 10/25G uplink density, ideal for aggregating traffic between switches or connecting to core networks.
- Hot-swappable design, allowing installation without downtime.
- Compatibility with C9200-L, C9200-CX, and C9200SK models (requires Cisco IOS XE 16.12.1 or later).
Performance and Use Cases
1. High-Speed Uplink Scenarios
The module’s 25G capability doubles throughput compared to standard 10G modules like the C9200-NM-4G, making it suitable for:
- Data center interconnects requiring low-latency, high-throughput links.
- Backhaul connectivity for campus networks with dense Wi-Fi 6/6E deployments.
- Storage area networks (SANs) and video streaming workloads.
2. Cost Efficiency
By leveraging auto-negotiation (10G/25G), organizations can future-proof their networks without immediately upgrading all transceivers.
Comparison with Other Cisco Modules
| Module | Ports/Speed | Best For |
|---|---|---|
| C9200-NM-2Y= | 2x 10/25G | High-bandwidth aggregation |
| C9200-NM-4G | 4x 1G | Legacy LAN environments |
| C9200-NM-2Q= | 2x 40G QSFP | Hyperscale data centers |
The C9200-NM-2Y= balances speed and affordability, bridging the gap between 10G and 40G solutions.
Addressing Common User Questions
Q: Does this module require additional licensing?
Yes. A Network Advantage license is needed to activate advanced features like QoS prioritization and encrypted traffic analytics.
Q: Can it operate in mixed-speed configurations?
Yes. One port can run at 25G while the other operates at 10G, optimizing costs during phased upgrades.
Deployment Best Practices
- Pair with Cisco-certified SFP28 transceivers (e.g., SFP-25G-SR-S) to ensure compatibility.
- Use Cisco DNA Center to automate uplink configuration and monitor performance.

Final Evaluation
The C9200-NM-2Y= is a strategic upgrade for enterprises needing flexible, high-speed uplinks without overhauling their entire infrastructure. While it lacks the raw power of 40G/100G modules, its 25G capability and backward compatibility make it a cost-effective choice for growing networks. However, teams should verify switch compatibility and budget for licensing to fully leverage its capabilities.
