Cisco N9K-C9372PX-E Nexus 9300 Data Center Switch
The Cisco N9K-C9372PX-E is a high-density fixed-port switch from the
Cisco Nexus 9300 Series, designed for enterprise data centers, cloud
infrastructure, virtualization environments, and high-performance network fabrics.
It provides 48 fixed 1/10 Gigabit Ethernet SFP+ ports together with
6 fixed 40 Gigabit Ethernet QSFP+ ports in a compact 1RU chassis.
With a 1.44 Tbps switching capacity and forwarding performance of
more than 1150 Mpps, the N9K-C9372PX-E is designed to handle
high-density data-center traffic and demanding east-west workloads. The SFP+ ports
provide flexible 1G/10G fiber connectivity, while the 40G QSFP+ interfaces can be
used for high-speed aggregation and fabric connections.

High-Density 1/10G SFP+ Connectivity
The 48 SFP+ interfaces provide high-density fiber connectivity for servers,
storage systems, virtualization hosts, leaf/access connections, and other
data-center equipment. Depending on the installed optics and network design,
these interfaces support 1 Gigabit or 10 Gigabit Ethernet connectivity.
40G QSFP+ Uplinks
Six fixed 40G QSFP+ ports provide high-bandwidth connectivity toward aggregation,
spine, or other data-center switching infrastructure. Supported transceivers,
cables, breakout configurations, and operating modes should be selected according
to Cisco compatibility documentation and the specific deployment.
Data Center Networking Applications
- Top-of-rack (ToR) data-center switching
- High-density 10 Gigabit server connectivity
- Leaf-spine network architectures
- Virtualized server and cloud infrastructure
- Enterprise data-center aggregation
- High-performance storage and server networks
- Data-center network migration and infrastructure upgrades
Cisco NX-OS and Network Architecture
The N9K-C9372PX-E is designed for Cisco Nexus environments using
Cisco NX-OS. Its Layer 2 and Layer 3 capabilities make it
suitable for data-center switching architectures where high port density,
high-speed uplinks, segmentation, automation, and operational consistency are
important.
Compatibility and Deployment
Compatibility with SFP, SFP+, QSFP+, breakout cables, and other optical
components depends on the exact Cisco-supported transceiver, cable, software
release, and network configuration. Always verify Cisco compatibility
documentation before purchasing op
