Description

The Cisco Nexus 9396PX is a high-performance data center switch designed for top-of-rack and middle-of-row deployment in enterprise and cloud environments. With 48 fixed 10GbE SFP+ ports and 12 fixed 40GbE QSFP+ ports, this 2RU switch delivers 1.92 Tbps switching capacity and ultra-low latency for demanding workloads. Enhanced Layer 3 capabilities provide advanced routing protocols including OSPF, BGP, and EIGRP, making it ideal for spine-leaf architectures, virtualized data centers, and high-frequency trading applications.

FAQs

Q: What is the difference between the N9K-C9396PX-FA-L3 and base N9K-C9396PX?
A: The FA-L3 SKU includes front-to-back (port-side exhaust) airflow and the Enhanced Layer 3 license pre-installed, which enables advanced routing protocols like OSPF, BGP, EIGRP, and policy-based routing. The base model requires separate licensing for these features.

Q: How many 40G uplink ports can this switch support?
A: The switch supports 12 active 40G QSFP+ uplink ports when equipped with the M12PQ uplink module, or 6 active ports with the M6PQ/M6PQ-E module. The uplink module is user-serviceable and sold separately.

Q: Is this switch suitable for Cisco ACI deployments?
A: Yes, the Nexus 9396PX can operate in both standalone NX-OS mode and Cisco ACI mode as a leaf switch. In ACI mode, it integrates with the Application Policy Infrastructure Controller (APIC) for automated policy-based network management.

Q: Does this switch support stacking or virtual port channels?
A: The Nexus 9300 series supports Virtual Port Channel (vPC) for dual-homing redundancy and enhanced bandwidth. Traditional stacking is not supported; spine-leaf architecture is the recommended topology for scale.

Q: What optics are compatible with the SFP+ and QSFP+ ports?
A: The switch supports Cisco 10GBASE SFP+ modules (SR, LR, LRM, copper DAC) and 40GBASE QSFP+ modules (SR4, LR4, BiDi). Third-party optics may work but are not officially supported by Cisco TAC.
