Questions & Answers
What is the Cisco Catalyst 9300 2x25GE Network Module (C9300-NM-2Y)?
The C9300-NM-2Y is a high-performance expansion module for the Catalyst 9300 Series, providing two SFP28 ports at 25 Gbps each to deliver ultra-fast uplink and aggregation capabilities.
Which Catalyst 9300 switches support the C9300-NM-2Y?
The C9300-NM-2Y is compatible with all Cisco Catalyst 9300 fixed-configuration switches, including models C9300-24T, C9300-48P, C9300-48T, and C9300-24P, when running IOS XE 16.12 or later.
What port types and speeds does the module offer?
This module features two SFP28 ports, each supporting 25 Gbps data rates for fiber-based uplink or aggregation with breakout to 4×10 Gbps on supported optics.
How does 25 Gigabit Ethernet enhance network performance?
By delivering 2.5× more throughput than 10 Gbps links, 25 GbE uplinks reduce congestion, improve application responsiveness, and provide future-proof bandwidth for high-density deployments.
Which optics are supported by the C9300-NM-2Y module?
The module supports Cisco SFP28 optics, including SR, LR, and CWDM variants, and is forward compatible with DAC and AOC cables certified for 25 GbE applications.
Can I mix the C9300-NM-2Y with other network modules in a single switch?
Yes, Catalyst 9300 switches allow you to install different network modules in available expansion slots, provided the total power and cooling budgets are not exceeded.
What is the maximum forwarding throughput of the C9300-NM-2Y?
When installed, each 25 Gbps port delivers line-rate forwarding up to 25 Gbps, enabling aggregated throughput of 50 Gbps for uplink traffic.
How do I install the Catalyst 9300 2x25GE Network Module?
Power down the switch, slide the C9300-NM-2Y into an available expansion slot until it clicks, secure with the captive screws, and power on the device to auto-detect the module.
What Cisco IOS XE software version is required?
The C9300-NM-2Y requires Cisco IOS XE 16.12.1 or later for full feature support, including enhanced visibility and SFP28 optical diagnostics.
Does the module support Cisco StackWise technology?
Yes, when installed in a stack member, the C9300-NM-2Y uplinks participate in Cisco StackWise-480 or StackWise-1T, ensuring high availability and unified management.
What are the module’s physical dimensions and power consumption?
The module measures 1.1 x 8.1 x 9.2 inches, weighs 0.8 lbs, and consumes up to 6 W under full-load conditions.
Are there any special cooling requirements?
No additional cooling is required. The module leverages the switch’s front-to-back airflow design, provided ambient conditions meet Cisco’s standard operating ranges.
What warranty and support are included with the C9300-NM-2Y?
The module comes with a limited lifetime hardware warranty and is eligible for Cisco SMARTnet® support for software updates, hardware replacement, and technical assistance.
Which use cases best suit the 2×25 GbE uplinks?
Ideal for data center leaf-spine architectures, high-density campus core aggregation, and bandwidth-intensive applications such as AI/ML workloads and multi-tenant environments.
How is licensing handled for the network module?
No separate license is required for basic port activation; advanced telemetry and visibility features may require Cisco DNA Advantage or Cisco DNA Premier licensing.
How can I monitor port status and performance?
Use CLI commands (show interfaces), Cisco DNA Center, or third-party SNMP/NetFlow tools to view real-time status, error counters, and optical diagnostics for each SFP28 port.
