Cisco N3K-C3016-BA-L3 | Nexus 3000 16-Port 40GbE QSFP+ Switch, Layer 3, 1.2 Tbps

Q: What is the difference between the N3K-C3016-BA-L3 and N3K-C3016-FA-L3?
A: The primary difference is airflow direction. The BA model features reversed airflow (port-side intake) for rear-to-front cooling, while the FA model has forward airflow (port-side exhaust) for front-to-back cooling. Both include the same Base and LAN Enterprise licenses. Choose the airflow direction that matches your data center cooling architecture.

Q: Can the QSFP+ ports be used for 10 Gigabit Ethernet connectivity?
A: Yes, each QSFP+ port can operate in native 40 Gigabit mode or 4 x 10 Gigabit breakout mode. You can use QSFP-to-SFP+ breakout cables to connect to 10GbE devices, providing up to 64 x 10GbE connections total. The switch supports both copper Twinax and fiber optic cabling solutions.

Q: What Layer 3 routing protocols are supported with the LAN Enterprise license?
A: The included LAN Enterprise license enables comprehensive Layer 3 unicast and multicast routing protocols including BGP, OSPF, EIGRP, RIPv2, PIM-SM, SSM, MSDP, and 64-way ECMP routing. The Base license is required to activate LAN Enterprise features.

Q: Is this switch suitable for high-frequency trading environments?
A: Yes, the Nexus 3016 is specifically designed for ultra-low-latency applications such as high-frequency trading and financial co-locations. It delivers wire-rate Layer 2 and Layer 3 switching with minimal latency, and the serialization benefits of 40 Gigabit Ethernet make it ideal for latency-sensitive workloads.

Q: Does this switch support redundant power supplies?
A: Yes, the Nexus 3016 can operate with a single AC power supply but supports an optional second power supply for full redundancy. This ensures continuous operation even if one power supply fails, making it suitable for mission-critical deployments.
