Table 1. Recovering system user configuration
Step Command

Using the console, restart the vRouter. The GRUB menu appears.

Select the Configuration Recovery option for the desired system software version.
Note: Versions earlier than 17.1 do not support configuration recovery from the GRUB menu.

Enter the relevant option from the Configuration Recovery list and press Enter. The action of the selected option is performed.

Up to five previous committed versions are displayed on each screen. You can navigate to the next or previous committed versions by using the Next or Previous options.

Note: The number of previous configurations displayed is set by the value of the system configuration management commit revisions. The default value is 20.

The commit configuration recovery menu also displays the commit comment to help you understand the details of the configurations.
