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. 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 (here, 1 is entered and the configuration returns to the previously committed configuation):

   [edit]

   user@switch# rollback 1

   load complete

   
   
2. Activate the configuration you have loaded:

   [edit]

   user@switch# commit
