Scheduling a System Reset
These sections describe how to schedule a system reset:
•
Scheduling a Reset at a Specific Time, page 20-10
•
Scheduling a Reset Within a Specified Amount of Time, page 20-10
You can use the
schedule reset
command to schedule a system to reset at a future time. This feature
allows you to upgrade software during business hours and schedule the system upgrade after business
hours to avoid a major impact on users.
You can also use the schedule reset feature when trying out new features on a switch. To avoid
misconfiguration or the possibility of losing network connectivity to the device, you can set up the
startup configuration feature and schedule a reset to occur in 30 minutes. You can then change the
configuration, and if connectivity is lost, the system will reset in 30 minutes and return to the previous
configuration.
