Loading a Previous Configuration File (CLI Procedure)

You can return to a previously committed configuration file if you need to revert to a previous configuration or if you have lost management access to the switch. The EX-series switch saves the last 50 committed configurations, including the rollback number, date, time, and name of the user who issued the commit configuration command.

Syntax


rollback (number)


Options


  • None — Return to the most recently saved configuration.
  • Number — Configuration to return to.
    • Range: 0 through 49. The most recently saved configuration is number 0, and the oldest saved configuration is number 49.
    • Default: 0

To return to a configuration prior to the most recently committed one:

  1. Specify the rollback number:
      [edit]
      user@switch# rollback number
      load complete

  2. Activate the configuration you have loaded:
      [edit]
      user@switch# commit
