Description

The Cisco Nexus 3264C-E is a high-density data center switch offering 64 QSFP28 ports with flexible 10/25/40/50/100 Gigabit Ethernet speeds and breakout capabilities. Designed for demanding data center environments, it delivers wire-rate Layer 2 and 3 switching with ultra-low 450ns latency and massive 12.8 Tbps total switching capacity. This 2RU switch features advanced NX-OS capabilities, MACsec security on 16 ports, and extensive programmability for cloud, virtualization, and big data workloads.

Features

Wire-rate Layer 2 and Layer 3 switching on all 64 ports
- Ultra-low latency of 450 nanoseconds for latency-sensitive applications
- 12.8 Tbps total switching capacity with 3.3 bpps forwarding rate
- MACsec encryption support on 16 ports for enhanced security
- 64-way Equal-Cost Multipath (ECMP) routing for scalable Layer 3 designs
- Virtual PortChannel (vPC) for active-active Layer 2 redundancy
- Flexible port breakout: 100G, 4 x 25G, or 2 x 50G per QSFP28 port
- 42 MB dynamic buffer allocation for optimized traffic handling
- Advanced buffer monitoring for real-time utilization visibility
- Cisco NX-OS with comprehensive programmability (Python, NX-API, REST APIs)
- Power-On Auto Provisioning (POAP) for zero-touch deployment
- Hot-swappable redundant power supplies and fans
- Support for both forward and reverse airflow for hot/cold aisle flexibility
- Embedded Event Manager (EEM) for automation and orchestration
- OpenStack, Linux containers, Puppet, and Chef integration
- Comprehensive routing protocols: BGP, OSPF, EIGRP, IS-IS, PIM
- Layer 2 features: VLAN, STP, LACP, LLDP, and advanced QoS
- Jumbo frame support up to 9216 bytes MTU

FAQs

Q: What port breakout options does the N3K-C3264C-E support?
A: Each QSFP28 port can operate natively at 100G or break out into 4 x 25G or 2 x 50G, allowing up to 128 x 25G ports total. The switch supports both fiber and copper cabling with flexible speed configurations from 10G to 100G.

Q: Is this switch suitable for spine-leaf data center architectures?
A: Yes, the Nexus 3264C-E is purpose-built for data center spine and leaf deployments. It supports 64-way ECMP routing for Layer 3 fat-tree designs, Virtual PortChannel (vPC) for redundancy, and ultra-low latency for demanding workloads including big data and cloud applications.

Q: What is the difference between the N3K-C3264C-E and N3K-C3232C models?
A: The 3264C-E offers 64 x 100G QSFP28 ports with 12.8 Tbps total capacity, while the 3232C provides 32 x 100G QSFP28 ports with 6.4 Tbps capacity. Both support MACsec and identical Layer 2/3 features, but the 3264C-E is a 2RU versus 1RU form factor for the 3232C.

Q: Does the N3K-C3264C-E require additional licenses for Layer 3 routing?
A: The N3K-C3264C-E ships with NX-OS and includes Layer 2 and Layer 3 routing capabilities. Advanced features may require additional licensing depending on the feature set needed. Contact your Cisco partner for specific licensing requirements.

Q: What type of transceivers are compatible with this switch?
A: The switch supports Cisco QSFP28, QSFP+, and compatible optical and copper transceivers including SR4, LR4, and direct-attach copper (DAC) cables. Breakout cables allow connectivity to 25G, 10G SFP28, and SFP+ devices for flexible migration and interoperability.
