Performance and Scale in a Small Form Factor

The Cisco Nexus 9372TX/9327TX-E Switch offers a line-rate layer 2 and layer 3 feature set in a compact form factor. It offers a flexible switching platform for both 3-tier and spine-leaf architectures as a leaf node. With the option to operate in Cisco NX-OS or Application Centric Infrastructure (ACI) mode, it can be deployed within small business, enterprise, and service provider architectures.

Features and Capabilities

The Cisco Nexus 9372TX/9327TX-E Switch has 48 1/10GBase-T ports that can operate at 100 Mbps, 1 Gbps, and 10 Gbps speeds and six Quad Small Form Pluggable Plus (QSFP+) uplink ports. All ports are line rate, delivering 1.44 Tbps of throughput in a 1-rack-unit (1RU) form factor. Nexus 9372TX/9327TX-E benefits are listed below.

Architectural Flexibility

  • Includes top-of-rack or middle-of-row copper-based server access connectivity
  • Includes a leaf node in a spine-leaf architecture for low-latency traffic flow and reduced convergence time in the event of a failure


  • Nexus 9372TX-E supports IP-based endpoint group (EPG) classification in ACI mode
  • Includes an enhanced version of Cisco NX-OS Software designed for performance, resiliency, scalability, manageability, and programmability
  • ACI-ready hardware infrastructure allows users to take full advantage of an automated, policy-based, systems management approach
  • Supports virtual extensible LAN (VXLAN) routing
  • An additional 25 MB buffer is included, surpassing competing switch offerings

Highly Available and Efficient Design

  • High-density, non-blocking architecture
  • Easily deployed into either a hot-aisle and cold-aisle configuration
  • Redundant, hot-swappable power supplies and fan trays

Simplified Operations

  • Power-On Auto Provisioning (POAP) support allows for simplified software upgrades and configuration file installation
  • An intelligent API offers switch management through remote procedure calls (RPCs, JSON, or XML) over a HTTP/HTTPS infrastructure
  • Python Scripting for programmatic access to the switch command-line interface (CLI)
  • Hot and cold patching, and online diagnostics

Investment Protection

  • A Cisco 40 Gb bidirectional transceiver allows for reuse of an existing 10 Gigabit Ethernet multimode cabling plant for 40 Gigabit Ethernet
  • Support for 100 Mb, 1 Gb, and 10 Gb access connectivity for data centers migrating access switching infrastructure to faster speeds
