A lot of times we need to make changes on a router or switch that could break connectivity, and often these need to be done from a remote location, and after hours. Instead of keeping someone in the office or on call, here is a much easier bailout. Before you begin to make the changes, issue the command reload in 10 to schedule a reload in 10 minutes (replace 10 in the command with the number of minutes if 10 doesn’t work.) After you make the changes, if you lose connectivity, the router reboots, reverting to the old configuration, or you can issue the reload cancel command to cancel the reload if everything goes well.
