FAQs

Q: Does this model have dedicated uplink ports?
A: No. All 64 QSFP+ ports are data ports; there are no separate dedicated uplink ports.

Q: Can I break out QSFP+ ports to 4x10G?
A: Yes, QSFP+ ports can typically break out to 4x10G with the appropriate DAC/AOC or breakout optics, subject to software and optics support.

Q: Which optics and cables are supported?
A: Standard QSFP+ 40G SR/LR/ER, CWDM/DWDM (where supported), and QSFP+ DAC/AOC are commonly supported. Refer to the platform transceiver compatibility list for exact SKUs.

Q: Is this platform ACI-capable?
A: This platform runs NX‑OS; it is not an ACI leaf/spine. It interoperates with ACI networks using standard L2/L3 and VXLAN EVPN.

Q: What license tier is required?
A: Base NX‑OS L2/L3 licensing is typical for core features; advanced features may require additional feature licenses depending on software release.
