## nv show system config auto-save

Shows if configuration auto save is enabled.

If auto save is disabled when you run the `nv config apply` command to apply a configuration setting, NVUE applies the pending configuration to become the applied configuration but does not update the startup configuration file (`/etc/nvue.d/startup.yaml`). To save the applied configuration to the startup configuration so that the changes persist after the reboot, you must run the `nv config save` command.

If auto save is enabled when you run the `nv config apply` command, NVUE saves the configuration to the startup configuration automatically when you run `nv config apply` so that you do not have to run the `nv config save` command.

- In Cumulus Linux 5.9 and later, auto save is enabled by default.
- In Cumulus Linux 5.8 and earlier, auto save is disabled by default.

### Version History

Introduced in Cumulus Linux 5.4.0

### Example

    cumulus@switch:~$ nv show system config auto-save
    state: disabled

## nv show system config snippet

Shows the file snippets you configure on the system.

### Version History

### Example

    cumulus@switch:~$ nv show system config snippet
    switchd.conf: |
      link_flap_window = 10
      link_flap_threshold = 5
