Cumulus Linux 5.9 User Guide

NVIDIA® Cumulus Linux is the first full-featured Debian bookworm-based, Linux operating system for the networking industry.

This user guide provides in-depth documentation on the Cumulus Linux installation process, system configuration and management, network solutions, and monitoring and troubleshooting recommendations. In addition, the quick start guide provides an end-to-end setup process to get you started.

Cumulus Linux 5.9 includes the NVIDIA NetQ agent and CLI. You can use NetQ to monitor and manage your data center network infrastructure and operational health. Refer to the NVIDIA NetQ documentation for details.

For a list of the new features in this release, see What's New. For bug fixes and known issues present in this release, refer to the Cumulus Linux 5.9 Release Notes.

Try It Pre-built Demos

The Cumulus Linux documentation includes pre-built Try It demos for certain Cumulus Linux features. The Try It demos run a simulation in NVIDIA Air; a cloud hosted platform that works exactly like a real world production deployment. Use the Try It demos to examine switch configuration for a feature. For more information, see Try It Pre-built Demos.

Open Source Contributions

To implement various Cumulus Linux features, NVIDIA has forked various software projects, like CFEngine Netdev and some Puppet Labs packages. Some of the forked code resides in the NVIDIA Networking GitHub repository and some is available as part of the Cumulus Linux repository as Debian source packages.

NVIDIA has also developed and released new applications as open source. The list of open source projects is on the Cumulus Linux packages page.
