For those who often work on remote Cisco device is very useful to have the opportunity to recover the previous configuration changes made (perhaps because it has lost connectivity …).
To do this it is possible to set an automatic reload, which will allow us to restart the router with its original configuration (startup-config) and recover the connection.
The command is as follows:
Router # reload in?
Delay before reload (mmm or hhh: mm)
Router # reload in 45
Router # reload in 45?
LINE Reason for reload
Router # reload in 45 For Test?
LINE
Router # reload in 45 For Test
System Configuration Has Been Modified. Save? [Yes / no]: n
