Cumulus Linux 5.2 includes the NVUE object model. After you upgrade to Cumulus Linux 5.2, running NVUE configuration commands replaces the configuration in files such as /etc/network/interfaces and /etc/frr/frr.conf and removes any configuration you add manually 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.
- Configure NVUE to ignore certain underlying Linux files 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.
