Frequently Asked Questions

Question:

What uses cases are best for the SN2201 ?
[email protected]
12-Oct-2026

Answer:

The SN2201 provides 48 1G BASE-T ports and four 100G QSFP28 uplinks. It is designed for OOB management and 1G top-of-rack access, rather than dense high-speed server access.

Question:

Does the SN2201 support both Cumulus Linux and SONiC out of the box?
[email protected]
12-Oct-2026

Answer:

This MSN2201-CB2FC ordering code includes Cumulus Linux. A compatible SONiC image is a separate NOS installation through ONIE; it is not an additional operating system already running out of the box. Other NOS options may be available as the ecosystem evolves.

Question:

How scalable is the SN2201 in a leaf-spine architecture?
[email protected]
12-Oct-2026

Answer:

It has four 100G QSFP28 uplinks for aggregation of its 48 1G access ports. That suits 1G/OOB access with high-speed uplinks; whether it fits a leaf/spine design depends on the required server speeds and oversubscription.

Question:

Can the SN2201 be integrated into existing monitoring and management systems?
[email protected]
12-Oct-2026

Answer:

Yes. The management interfaces and APIs are provided by the selected NOS release. With Cumulus Linux, match your monitoring and automation tools to its documented SNMP, NVUE API and telemetry features; do not assume every release has RESTCONF or gNMI.

Question:

What kind of support does NVIDIA provide for this switch?
[email protected]
12-Oct-2026

Answer:

Hardware and software service follow the NVIDIA support entitlement purchased for this switch. Confirm replacement terms, software access and response hours in the quote; support is not established by the hardware model alone.

Question:

Does it support Onyx still?
[email protected]
12-Oct-2026

Answer:

MSN2201-CB2FC is supplied with Cumulus Linux, not Onyx. Use a Cumulus Linux release qualified for the SN2201. An Onyx support entitlement should not be assumed from this SKU.
