A compact 1RU 32-port 800G switch
The Cisco Nexus 9232E Switch is the first switch with 800 Gigabit-capable ports in the Cisco Nexus 9000 Series portfolio. This switch offers 32 QSFP-DD800 ports in the compact 1RU that can support 2x400G, 8x 100G, 4x 25G, and 4x 10G Ethernet interfaces.
Data centers continue to evolve to support next-generation applications such as AI/ML that drive massive bandwidth growth in intra data center traffic. To support this growth, data center operators require compact, high-capacity, high-speed, and highly efficient switches.
The Cisco Nexus 9232E Switch is built with a power-efficient, high-performance 25.6Tbps ASIC that supports dynamic flowlet load balancing, fully shared on-die packet buffering, and line-rate performance for small packets. The ASIC provides these capabilities, without compromising on features and power efficiency, that make the Cisco Nexus 9232E Switch ideal for supporting high-bandwidth applications across data centers of varying sizes and scale. Furthermore, these capabilities are complemented with the robust functionality of Cisco NX-OS software and the extensive visibility provided by Cisco Nexus Dashboard.
This makes the Cisco Nexus 9232E Switch an ideal compact, high-port-density, high-capacity data center spine that supports high-speed connectivity for massively scaled out fabrics. The ability to also support lower-speed ports in breakout mode makes the switch a compelling high-port-density leaf switch as well.

Compact high-density 400GE connectivity
The Cisco Nexus 9232E Switch is the most compact 25.6Tbps switch and can also provide up to 64 line rate 400GE ports in a 1RU fixed chassis. This allows data center operators to build scaled out fabrics without compromising on high-speed port density and rack space need for spine switches. Furthermore, the total capacity and high-density 400G ports make this an ideal spine switch for multi-tier data center fabrics.
Flexibility and Backwards Compatibility
The Cisco Nexus 9232E switch supports 32 QSFP-DD800 ports. These ports are compatible with appropriate QSFP-DD (400G), QSFP28 (100G), and QSFP+(40G) transceivers. This enables the Cisco Nexus 9232E switch to be gracefully deployed into data center fabrics that are already deployed with 400G or 100G fabric speeds.
Buffering
The Cisco Nexus 9232E Switch supports a fully shared buffer memory architecture that allows the switch to absorb bursts up to the available shared memory size. This shared memory architecture also improves power efficiency by minimizing the number of read/write operations to just one of each.
Timing and synchronization
The Cisco Nexus 9232E Switch supports IEEE 1588 PTP and Synchronous Ethernet with Class C accuracy.
Power and fan redundancy
The Cisco Nexus 9232E Switch supports high-efficiency hot-swappable AC, DC, or high voltage AC/DC power supplies that provide 1 + 1 power supply redundancy. The switch also supports six hot-swappable variable speed fan trays.
The Cisco Nexus 9232E Switch would use the XF2 tier Cisco Data Center Network (Cisco DCN) Premier, Advantage, and Essentials subscription licenses.
