N3K-C3264Q Overview
N3K-C3264Q is the Nexus 3264Q, 64 QSFP+ ports, 2RU switch. The Cisco Nexus 3264Q Switch is a Low Latency, ultra-high-density, power-efficient, 40-Gbps switch designed for the data center. This compact, two-rack-unit (2RU) model offers wire-rate Layer 2 and Layer 3 switching on all ports with latency between 515-700ns. It runs the same modern Cisco NX-OS image that also supports the Cisco Nexus 9000 Series Switches. It provides a comprehensive feature set and simplifies image management. The robust programmability features help enable organizations to run today’s applications while also preparing them for demanding and changing application needs such as big data, cloud services, and virtualization.

Product Details
The Cisco Nexus 3264Q provides the following main benefits:
1. Wire-rate Layer 2 and 3 switching on all ports up to 5.12 terabits per second (Tbps) and up to 3.8 billion packets per second (bpps)
2. Robust programmability, with support for Cisco NX-API, Linux containers, XML and JavaScript Object Notation (JSON) APIs, OpenStack plug-in, Python, and Puppet and Chef configuration and automation tools
3. High performance and scalability with a two-core CPU with 8 GB DRAM making it excellent for massively scalable data centers and big data applications
4. Flexibility
(1) Cisco QSFP 40-Gbps bidirectional (BiDi) transceiver technology allows the reuse of existing 10-Gbps cabling, for a smooth transition from 10 to 40 Gigabit Ethernet infrastructure in data centers.
(2) Both fiber and copper cabling solutions are available for 40-Gbps connectivity, including 40G BiDi, 40G active optical cable (AOC), 40G twinax cable, and 40G LR4 optics as well as QSA for 10G connectivity.
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 solution uses hot-swappable power-supply units (PSUs) and fans.
6. Modern NX-OS operating system with comprehensive, proven innovations
(1) PowerOn 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).
