display rollback state

display rollback state

Function

The display rollback state command displays the rollback status of the system.

Format

display rollback state

Parameters

None

Views

All views

Default Level

1: Monitoring level

Usage Guidelines

This command enables you to:

  • Check whether the rollback function is enabled.
  • Preview the files used after a version rollback to avoid an unexpected rollback.
  • The rollback status can be displayed only if the rollback command can be used. Therefore, the display rollback state command can display the rollback status only when the following conditions are met: the system software for rollback exists, the current software package is different from the previous system software package, and no new package is specified for next startup using the startup system-software command.
  • If no rollback system software exists, a message "Rollback function is disabled in current state" will be displayed when you run the display rollback state command.

Example

# Preview the files used after a version rollback. The names and paths of various startup files used in the rollback version are displayed if the rollback function is enabled in the system.
