Discussion

The time is in 24-hour (military) format, so to specify a time after 12 p.m., use the
following command:
[edit]
aviva@router1# commit at 22:45
configuration check succeeds
commit at will be executed at 2005-02-25 22:45:00 PST
Exiting configuration mode
To schedule the activation of a configuration to occur on another day, use the full
date and time:
[edit]
aviva@router1# commit at "2005-02-26 10:45"
configuration check succeeds
commit at will be executed at 2005-02-26 10:45:00 PST
Exiting configuration mode
To cancel a commit operation scheduled with the commit at command, use the following
command:
aviva@router1> clear system commit
Pending commit cleared
Discussion
Sometimes you want to delay the activation of a configuration, scheduling it to occur
at some later time. For example, if you are a network provider and have a service
window in which network changes are made, you want the new configuration to
take effect during that window. Or, if you are making changes on a number of routers,
you might want the changes to take effect on all the routers at the same time or
within the same time window, especially if you are making changes to routing protocols
that might affect routing and route convergence across the network.
One way to schedule the activation of a configuration is to use the commit at command.
The first two commands in this recipe commit the configuration at a specific
time on the current day, one at 10:45 a.m. and the second at 10:45 p.m. The third
command schedules the commit at 10:45 a.m. on another day.
Verify that the commit command has actually executed by looking at the timestamp
on the currently running configuration file:
aviva@router1> file list detail /config
/config:
