rollback

Syntax

rollback <number> 

Description

Return to a previously committed configuration. The software saves the last 50 committed configurations, including the rollback number, date, time, and name of the user who issued the commit configuration command.

The currently operational JUNOS software configuration is stored in the file juniper.conf, and the last three committed configurations are stored in the files juniper.conf.1, juniper.conf.2, and juniper.conf.3. These four files are located in the directory /config, which is on the router's flash drive. The remaining 46 previous committed configurations, the files juniper.conf.4 through juniper.conf.49, are stored in the directory /var/db/config, which is on the router's hard disk.

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.
