Description

The Cisco Nexus 3132Q is a high-performance data center switch delivering 32 ports of 40 Gigabit Ethernet in a compact 1RU form factor. Each QSFP+ port supports native 40GbE or 4x10GbE breakout mode, offering deployment flexibility for leaf-spine architectures. With 2.5 Tbps switching capacity, line-rate Layer 2 and Layer 3 forwarding, and comprehensive routing protocols including BGP, OSPF, and EIGRP, this switch is optimized for modern data center environments requiring low-latency, high-throughput connectivity.

FAQs

Q: What is the difference between the 3132Q, 3132Q-X, and 3132Q-XL models?
A: The base 3132Q is the original model with 4GB RAM and 1.5GHz CPU. The 3132Q-X is a hardware revision with improved power efficiency (40W less), enhanced CPU performance, and different port layout. The 3132Q-XL offers 8GB RAM, 16GB Logflash, and a 2.5GHz CPU for advanced workloads requiring additional memory.

Q: Can I use 10GbE transceivers with this switch?
A: Yes. Each of the 32 QSFP+ ports can operate in 4x10GbE breakout mode using QSFP-to-4xSFP+ breakout cables, supporting up to 128 ports of 10GbE. Additionally, the switch has 4 dedicated SFP+ ports that accept 10GbE and 1GbE transceivers natively.

Q: What Layer 3 routing protocols are supported with the LAN Enterprise license?
A: The LAN Enterprise license enables full Layer 3 routing including BGP, OSPFv2, EIGRP, RIPv2, static routing, HSRP, VRRP, 64-way ECMP, VRF-Lite, PIM-SM, PIM-SSM, MSDP, and policy-based routing. This makes the switch suitable for leaf-spine data center topologies and enterprise campus core deployments.

Q: What does forward airflow mean and why does it matter?
A: Forward airflow (FA) means air enters through the fan tray and power supplies at the front and exhausts through the port side at the rear. This configuration is designed for hot-aisle/cold-aisle data center layouts where the port side faces the hot aisle. The switch also supports reversed airflow (BA) models for alternate cooling strategies.

Q: Is this switch compatible with Cisco ACI fabric deployments?
A: The Nexus 3132Q can operate in standalone NX-OS mode or as part of a Cisco ACI fabric when programmed with ACI firmware. When used in ACI mode, it functions as a leaf switch and requires an APIC controller. Consult Cisco compatibility documentation to confirm ACI support for your specific firmware version.
