FAQs

Q: What license bundle is included with the N3K-C3132Q-BD-L3?
A: This SKU includes both the Base license (N3K-BAS1K9) for comprehensive Layer 2 features and the LAN Enterprise license (N3K-LAN1K9) which enables full Layer 3 routing capabilities including OSPF, EIGRP, BGP, PIM, VRRP, HSRP, and advanced multicast protocols.

Q: Can I use 10GbE optics directly in this switch?
A: Yes, the switch includes 4 dedicated SFP+ ports multiplexed with the first QSFP+ port. Additionally, each of the 32 QSFP+ ports can operate in 4x10GbE breakout mode using QSFP-to-SFP+ breakout cables or appropriate transceivers, supporting up to 104x 10GbE connections.

Q: What is reverse airflow and when should I use it?
A: Reverse airflow (port-side intake) means air enters through the front ports and exhausts through the rear fan tray and power supplies. This airflow direction is ideal for hot-aisle/cold-aisle data center deployments where switches face the cold aisle, ensuring proper thermal management and energy efficiency.

Q: Is this switch suitable for leaf-spine data center architectures?
A: Absolutely. The Nexus 3132Q is purpose-built for leaf-spine fabrics, offering wire-rate 40GbE connectivity, support for Virtual Port Channel (vPC) technology, 64-way ECMP routing for Layer 3 fat-tree designs, and comprehensive VXLAN capabilities for overlay networks.

Q: What routing protocols are supported with the LAN Enterprise license?
A: The LAN Enterprise license enables a full suite of routing protocols including OSPFv2, EIGRP, BGP, RIPv2, VRRP, HSRP, static routing, policy-based routing (PBR), and multicast protocols such as PIM-SM, PIM-SSM, and MSDP.
