  • 1.  URGENT: Configuration undo

    Posted 10-23-2009 02:11

    Hi,

     

    I have been configuring some EX 4200 switches and accidentally input a command which if i commit will destroy my configurations and probably my employment.

     

    I need to remove these configurations, and undo to last known config whilst not taking the switch cluster down.

     

    Crisis!

     

    Please help

    Hi,

     

    if you changed configuration in the config mode then just do "rollback 0" and that is it.

     

    Kind Regards

    When you allready commited the changes: rollback 1.

     

    To check for the right rollback:

     

    show  | compare

    Hey Screenie - not to "nitpick" to much - but "show | compare" simply compares current config to last prior committed.

     

    Syntax is "show | compare rollback X" where "X" equals 1 of 50 prior configs - (for the benefit of the original questioner.....)

    You're right of course. I wanted to lookup the exact syntax compare <nr> or compare rollback <nr>, a sybtax I can't memorize, but forgot and posted to fast. Glad you noticed it. Have a nice weekend!
