Bulk operations on Nvidia (Mellanox) get expensive fast if you do them serially. Cumulus Linux / NVOS / SONiC tolerates parallel pushes well, but only if you respect the rate limits and the activation order on the SN2010 family. Get either wrong and you create a self-inflicted outage.

I always wrap automation runs in pre- and post-check captures. cl-support (Cumulus) / show techsupport (SONiC) before and after gives you a diff that Nvidia Enterprise Support can act on if anything looks off later.

What follows is a battle-tested pattern. Adapt the concurrency to your environment. there is no universal right answer, only ranges that work.

What this guide covers

How to deploy with a Python script (paramiko / netmiko / native API) for Nvidia (Mellanox) SN2010 (Cumulus Linux / NVOS / SONiC).

Step-by-step

  1. Choose the automation surface: vendor controller, API, or CLI scripting.
  2. Verify reachability + credentials from your automation host.
  3. Test the change on a single device + maintenance window.
  4. Roll out in waves of 10-20 devices to limit blast radius.
  5. Pre-collect baseline, push the change, post-collect; diff.
  6. Roll back any device whose post-check fails.

Sample CLI invocation

# Manual baseline
nv show system
nv show platform inventory
nv show interface

# Push change (via vendor CLI)
nv config (NVUE)
nv set interface swp1 ip address 10.0.0.1/24
nv config apply
nv config save

# Verify
nv show interface

Frequently asked questions

Will this work on my specific Cumulus Linux / NVOS / SONiC version?

The procedure reflects current Cumulus Linux / NVOS / SONiC behaviour. Older releases may need minor syntax adjustments, use the CLI help (? or tab-completion) to verify.

Should I open a Nvidia Enterprise Support case immediately?

Open one if you suspect hardware failure or the symptom persists after a maintenance-window reload. Make sure your support entitlement is active first.

Where can I find the Nvidia (Mellanox) official documentation?

https://docs.nvidia.com/networking/: search the product family + feature name.

Is this procedure safe in production?

Test in a lab or maintenance window first. Capture pre-change state so you can roll back.

Reference material, not professional advice. Validate against your specific Cumulus Linux / NVOS / SONiC version and test in a non-production environment before applying.

What changed recently?

Fault diagnosis on a Nvidia device goes faster when you map the symptom to a recent change:

The answer narrows the root cause to a manageable subset.

Before you start

A few things to confirm so the Nvidia device fix goes cleanly:

Quick verification

Before you walk away from a Nvidia device fix, run through:

1. Reproduce the original trigger, does the issue reappear? 2. Check the device's status / health screen for any new alerts. 3. Confirm paired devices (app, hub, controller) reconnected. 4. Save / commit any configuration changes per the device's normal workflow. 5. Note the change in your maintenance log with date + firmware version.

More frequently asked questions

Can I roll this back if something breaks?

Yes for software-level changes (firmware rollback, config rollback). Hardware changes are usually one-way. Always back up settings before starting.

Why is this happening on a brand-new unit?

Out-of-box defects do occur. If you've owned the device under 30 days and the symptom persists after a factory reset, escalate to the seller for replacement under DOA terms before opening a manufacturer support case.

Should I update firmware first or last?

Update firmware first if a release note specifically mentions your symptom. Otherwise, finish the troubleshooting flow first, then update; that way you can isolate whether the update or the underlying fix solved it.

What if the fix returns after a reboot?

Persistent fault returns mean either: a hardware fault (escalate), a configuration that's being overwritten by a sync source (check cloud profiles), or a regression in a recent firmware update (rollback).

How long does this fix usually take?

Most users complete the steps in 20-45 minutes the first time, and 5-10 minutes on subsequent runs once the menu paths are familiar.
