FAQs

Q: What license bundles are included with the N3K-C3016-BD-L3?
A: This SKU includes both the Base license (N3K-BAS1K9) and LAN Enterprise license (N3K-LAN1K9), enabling full Layer 3 unicast and multicast routing protocols including BGP, OSPF, EIGRP, RIPv2, and PIM out of the box.

Q: Can the QSFP+ ports be used for 10 Gigabit Ethernet connections?
A: Yes, each QSFP+ port can operate in either native 40 Gigabit Ethernet mode or 4x 10 Gigabit Ethernet mode using QSFP-to-SFP+ breakout cables, supporting both fiber and copper cabling solutions.

Q: What airflow direction does this model support?
A: The N3K-C3016-BD-L3 features port-side intake (reversed) airflow, meaning air is drawn in from the port side and exhausted from the fan side. This is important for data center hot aisle/cold aisle configurations.

Q: What is the typical use case for the Nexus 3016?
A: The Nexus 3016 is designed for high-performance, ultra-low-latency data center applications including financial trading platforms, top-of-rack (ToR) deployments, and high-density 40GbE or 10GbE aggregation with Layer 3 capabilities.

Q: Does this switch support redundant power supplies?
A: Yes, the Nexus 3016 supports dual redundant DC power supplies for enhanced reliability, though it can operate with a single power supply. Each DC PSU is rated at 350W.
