Cumulus Linux 5.7 includes the NVUE object model. After you upgrade to Cumulus Linux 5.7, running NVUE configuration commands might override configuration for features that are now configurable with NVUE and removes configuration you added manually to files or with automation tools like Ansible, Chef, or Puppet. To keep your configuration, you can do one of the following:
- Update your automation tools to use NVUE.
- UNABLE TO FIND LINK when applying configuration changes.
- Use Linux and FRR (vtysh) commands instead of NVUE for all switch configuration.
Cumulus Linux 3.7, 4.3, and 4.4 continue to support NCLU. For more information, contact your NVIDIA Spectrum platform sales representative.
