Description

The Cisco Nexus 3132Q-XL is a high-performance 1RU data center switch delivering 32 ports of 40 Gigabit Ethernet via QSFP+, each capable of breakout to 4x 10GbE. Ideal for leaf-spine architectures and high-density environments, it provides 2.5 Tbps switching capacity, 1.4 Bpps forwarding rate, and full Layer 2 and 3 functionality with NX-OS. With 8 GB memory, 2.5 GHz CPU, and support for both forward and reverse airflow, this switch is well-suited for modern data centers requiring cost-effective, power-efficient, line-rate performance.

FAQs

Q: Can the QSFP+ ports be used for 10 Gigabit Ethernet connectivity?
A: Yes, each of the 32 QSFP+ ports supports breakout mode, allowing operation as 4x 10 Gigabit Ethernet ports using appropriate breakout cables or transceivers, providing up to 128x 10GbE ports total.

Q: What licensing is required for Layer 3 features?
A: When used in NX-OS native mode, the N3K-LAN1K9 license is required to enable Layer 3 routing features. In Nexus 9000 mode, licensing requirements differ. Verify your deployment mode and feature requirements before purchase.

Q: Is this switch suitable for leaf-spine data center architectures?
A: Absolutely. The N3K-C3132Q-XL is designed as a cost-effective, high-performance leaf or access switch for modern data center fabrics, supporting technologies like vPC, VXLAN, ECMP, and low-latency forwarding ideal for spine-leaf topologies.

Q: What airflow options are available?
A: The switch supports both forward airflow (port-side exhaust) and reverse airflow (port-side intake) configurations with corresponding fan modules and power supplies, allowing flexible deployment in hot-aisle or cold-aisle data center designs.

Q: What is the end-of-life status of this product?
A: Cisco announced end-of-sale for the Nexus 3132Q-XL in January 2023. While new purchases are no longer available from Cisco, the switch remains supported with software updates and RMA services during the end-of-life support period. Consider newer Nexus models for long-term deployments.
