  • 1.  Request System Reboot At Juniper JUNOS Explained.

    Posted 06-28-2011 19:30

    Hello. I just would like to take a moment to clear something up, which has been bugging me for a while now.

     

    I don't believe that the bulletins which Juniper has provided regarding the command

     

    request system reboot at are correct.

     

    What I would like to do is provide 3 examples to make this functional and useful for anyone working on devices.

     

    Scenario 1:

    I would like to reboot the router at 00:00 tomorrow, and today is June 28th, 2011, command to run:

     

    Syntax:

    request system reboot at yymmdd

    Example:

    request system reboot at 110629

     

    Scenario 2:

    I would like to reboot the router tomorrow at 04:00 (4 am), and today is June 28th, 2011, command to run:

     

    Syntax:

    request system reboot at yymmddhhmm

    Example:

    request system reboot at 1106290400

     

    Scenario 3:

    I would like to reboot the router tomorrow at 17:00 (5 pm), and today is June 28th, 2011, command to run

     

    Syntax:

    request system reboot at yymmddhhmm

    Example:

    request system reboot at 1106291700

     

    Thanks, and I hope this clarifies for those who have been looking for this information.

    Hello,

    You almost got it right except one needs to specify year in 4-digit format. Year in 2-digit format does not pass sanity check

    Here is what I just tried out:

    Reboot the system at 110107? [yes,no] (no) yes

    error: that time is already past.

    Reboot the system at 110701? [yes,no] (no) yes

    user@root>

     

    I believe it might have problems with leading 0's when entering this date format.

     

    Can you try it out on your machine? I'm running JUNOS 11.1R2.3

    Of course.

    If one tries 2-digit year _with_ hours and minutes specified, then all is fine:

     

    user@host> request system reboot at 1107011200 
    Reboot the system at 1107011200? [yes,no] (no) yes 
    
    Shutdown at Fri Jul  1 12:00:00 2011.
    [pid 8435]
    
    {master}
    user@host> clear system reboot 
    reboot requested by remote at Fri Jul  1 12:00:00 2011
    [process id 8435]
    Terminating...
    
    {master}
    user@host> request system reboot at 1107010000    
    Reboot the system at 1107010000? [yes,no] (no) yes 
    
    Shutdown at Fri Jul  1 00:00:00 2011.
    [pid 8453]

     But if one tries 2-digit year _without_ hours/minutes hoping to schedule reboot at midnight, then sanity check prevents that:

     

    {master}
    user@host> request system reboot at 110701        
    Reboot the system at 110701? [yes,no] (no) yes 
    
    error: that time is already past.
    
    {master}
    user@host> show system reboot 
    No shutdown/reboot scheduled.

     HTH
