Port Configuration & Speed Flexibility

The module features 8 x SFP28 downlink ports, each supporting 1 Gigabit Ethernet (SFP), 10 Gigabit Ethernet (SFP+), and 25 Gigabit Ethernet (SFP28) on a single port. This multi-rate design enables seamless migration from legacy 1G/10G infrastructure to modern 25G high-speed backbones without costly chassis replacement, protecting the network's long-term investment. Users can install Cisco-approved SFP/SFP+ and SFP28 transceivers, DAC cables, or AOCs on a port-by-port basis to mix speeds precisely where needed.

Performance & Deployment

The C9300X-NM-8Y offers total uplink bandwidth sufficient for large-scale access layer or distribution deployments. Typical applications include upgrading campus distribution layers to 25G uplinks to a core switch, adding 10G fiber uplinks to IDFs, or providing mixed-speed connectivity to servers, firewalls, and WAN routers. Its hot-swappable design supports online insertion and removal (OIR) with zero switch downtime, minimizing network disruption during capacity expansions or hardware upgrades.

 

Compatibility & Ideal Scenarios

The C9300X-NM-8Y is compatible with all Catalyst 9300X models natively, such as the C9300X-24Y and C9300X-12Y, and integrates seamlessly with the StackWise-1T stacking architecture and Cisco IOS XE feature set including full Layer 2/Layer 3 switching, QoS, MACsec, and IPsec security. Ideal for large campus access and distribution layers, SD-Access fabric deployments, and high-throughput PoE access aggregates requiring 25-gigabit uplink capacity to future-proof the network.
