Line-rate traffic throughput (both Layer 2 and 3) on all ports
Configurable maximum transmission unit (MTU) of up to 9216 bytes (jumbo frames)
32 QSFP28 ports; each supports native 100 Gigabit Ethernet and 4 x 25 Gigabit Ethernet modes
2 redundant power supplies
4 redundant (3+1) fans
Management, console, and USB flash-memory ports
The Cisco Nexus 3232C provides the following main benefits:
1. Wire-rate Layer 2 and 3 switching on all ports, with up to 6.4 terabits per second (Tbps) and up to 3.3 billion packets per second (bpps)
2. Robust programmability, with support for Cisco NX-API, Linux containers, XML and JavaScript Object Notation (JSON) APIs, the OpenStack plug-in, Python, and Puppet and Chef configuration and automation tools
3. High performance and scalability with a four-core CPU, 8 GB of DRAM, and 16 Mb of dynamic buffer allocation, making the switch excellent for massively scalable data centers and big data applications
4. Flexibility
(1) The QSFP28 port can be configured to work as 4 x 25-Gbps ports, offering deployment flexibility, with up to a maximum of 128 x 25-Gbps ports.
(2) Both fiber and copper cabling solutions are available for 10-, 25-, 40-, 50-, and 100-Gbps connectivity, including active optical cable (AOC) and direct-attached cable (DAC).
5. High availability
(1) Virtual PortChannel (vPC) technology provides Layer 2 multipathing through the elimination of Spanning Tree Protocol. It also enables fully utilized bisectional bandwidth and simplified Layer 2 logical topologies without the need to change the existing management and deployment models.
(2) The 64-way equal-cost multipath (ECMP) routing enables the use of Layer 3 fat-tree designs. This feature allows organizations to prevent network bottlenecks, increase resiliency, and add capacity with little network disruption.
(3) Advanced reboot capabilities include hot and cold patching and fast reboot capabilities.
(4) The switch uses hot-swappable power-supply units (PSUs) and fans.
6. Purpose-built NX-OS operating system with comprehensive, proven innovations
(1) Power-on auto provisioning (POAP) enables touchless bootup and configuration of the switch, drastically reducing provisioning time.
(2) Cisco Embedded Event Manager (EEM) and Python scripting enable automation and remote operations in the data center.
(3) Advanced buffer monitoring reports real-time buffer utilization per port and per queue, which allows organizations to monitor traffic bursts and application traffic patterns.
(4) EtherAnalyzer is a built-in packet analyzer for monitoring and troubleshooting control-plane traffic and is based on the popular Wireshark open-source network protocol analyzer.
(5) Complete Layer 3 unicast and multicast routing protocol suites are supported, including Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), Enhanced Interior Gateway Routing Protocol (EIGRP), Routing Information Protocol Version 2 (RIPv2), Protocol Independent Multicast sparse mode (PIM-SM), Source-Specific Multicast (SSM), and Multicast Source Discovery Protocol (MSDP).
