Description

The Cisco Nexus 3232C is a high-performance data centre switch delivering 32 ports of 100 Gigabit Ethernet QSFP28 connectivity in a compact 1RU form factor. Designed for top-of-rack and spine-leaf deployments, it provides 6.4 Tbps switching capacity with ultra-low 450ns latency, wire-rate Layer 2 and Layer 3 switching, and advanced programmability via Cisco NX-OS. Ideal for big data, cloud, and virtualised environments requiring high-density 100G connectivity with flexible breakout support for 10/25/40/50 Gigabit Ethernet.

FAQs

Q: What is the difference between the N3K-C3232C and N3K-C3232C-OE SKUs?
A: The N3K-C3232C-OE is the Open Environment edition that ships without a pre-installed software license tier, allowing you to purchase and install the appropriate NX-OS license separately. The base N3K-C3232C may include bundled licenses depending on the SKU variant. Both use the Nexus 9000 licensing scheme.

Q: Can I use 10G or 25G transceivers in the QSFP28 ports?
A: Yes, each QSFP28 port supports flexible breakout configurations. You can use splitter cables or optical transceivers to operate each port as 4x 25G, 4x 10G, 2x 50G, 1x 40G, or native 1x 100G, giving you deployment flexibility and investment protection as you scale from 10G to 100G.

Q: Is this switch suitable for spine-leaf data centre architectures?
A: Absolutely. The Nexus 3232C is specifically designed for high-density 100G spine-leaf fabrics and top-of-rack deployments. Its 6.4 Tbps throughput, low latency, and support for advanced Layer 3 routing protocols such as BGP, OSPF, EIGRP, and PIM-SM make it ideal for modern data centre topologies.

Q: Does the Nexus 3232C support automation and programmability?
A: Yes, it offers comprehensive programmability features including NX-API, Linux containers, Python scripting, JSON/XML APIs, Puppet and Chef integration, and OpenStack plug-ins. These tools enable infrastructure-as-code workflows, network automation, and seamless integration with DevOps pipelines.

Q: What Layer 3 routing features are supported?
A: The Nexus 3232C supports a complete Layer 3 routing suite including BGP, OSPF, EIGRP, RIPv2, PIM-SM, SSM, MSDP, HSRP, VRRP, and Unicast Reverse-Path Forwarding. It also supports advanced features like vPC for Layer 2 multipathing and ECMP for scalable, resilient network designs.
