The Cisco 'reload' command is used on almost all IOS Cisco networking devices (routers, switches etc) to restart (or reboot) the appliance.

Use this procedure to upgrade the ROMMON for the Cisco ASR 1001-X Router: SUMMARY STEPS (Optional) Run the show platform command or the show rom-monitor slot command to see the current release number of ROMMON on the hardware.; If the ROMMON image has not been copied onto the router, copy the PKG file that is made available as part of this ROMMON release onto the bootflash:. Not everyone knows that the reload command permits to schedule a reboot system; for instance, to plan a night router restart or during a critical configuration (AAA, vty, and so on). There are two ways to schedule a reload system: at: at a specific time/date in: after a time interval The ‘at' keyword permits to. If you go to global configuration mode, you can type reload and then hit the question mark. It shows you your choices. One of the choices is reload in. Further review of the command shows that if you set the reload time to 15 minutes, for example, this will give you a fifteen minute window in which to perform the task at hand. This video describes how to use the Cisco Reload command. In addition, it provides some strategies for using this command.
Use this command to reload at a specific time. Reload at 00:00. Proceed to configure the router as needed. As long as no configuration changes are saved, the router will revert to its previous configuration when it reloads. If configuration changes are successful, this code will stop the pending reload: reload cancel.
This command might seem very basic but it has some interesting practical applications that we will see later in this article.
Basic Command Usage
As we have said above, the basic usage of this command is to reload the IOS operating system of the router or switch. Its the same as rebooting a computer.
If the current running configuration is modified and not saved to flash, the device prompts you to save the configuration.
The following example shows how to immediately reload a Cisco device:
CiscoRouter# reload
Another useful trick to know is to verify first the stored IOS image on the device before reloading:
CiscoRouter# reload /verify
The above will first perform a signature verification and file integrity check on the stored bootflash image file before reloading the appliance. After the verification is done the system will ask you again if you want to reboot the device.
CiscoRouter# reload [text specifying the reason]
e.g CiscoRouter# reload testing of Access Control List
The above specifies the reason of reloading the system.
How to schedule a reload
Now this is the useful practical application of the reload command we have mentioned at the beginning.
By scheduling a reload at some specified time in the future allows the administrator to make critical changes to the configuration that might drop connectivity or have some other traffic implications.
If something unexpected happens after the configuration change, the device will reboot by itself in let's say 2 minutes from now thus restoring the previous state of the network.
Let's see how reload scheduling works:
There are two keywords that you can specify for reload scheduling:
reload at [specific date and time]
reload in [minutes]
Examples:
Luke nguyen casino brisbane ct. CiscoRouter# reload at 14:00
The above will reload the router at 2:00pm in the current date.
CiscoRouter# reload at 14:00 jan 10
The above will reload the router at 2:00pm on January 10.
Both of the above commands assume that you have correct clock settings configured on the device (NTP or manual system clock setting).
CiscoRouter# reload in 2
The above will reload the router in 2 minutes from now. Very useful as we will see in the special case below.
CiscoRouter# show reload
The above shows the current state of the reload command. If you have scheduled a reload operation after some time from now, the above command will show the exact time when the device will reboot.
CiscoRouter# reload cancel
The above will abort any scheduled reload operation.
Practical Use Case of Scheduling a Reload
Assume you are connected remotely to a router on the other side of the world and you are configuring some 'dangerous' commands such as changing an IP address on an interface, applying Access Control Lists, making changes to a dynamic routing protocol etc.
The above configuration modifications can kill your connection to the appliance, interrupt traffic communication, lock you out of the device etc. By scheduling a reload will provide a 'safety net' for the above unexpected situations.
Let's see what to do if you are working remotely on a Cisco device:
Step 1:
Cisco Reload In 5 Minutes
First save the current working configuration before making any changes:
CiscoRouter# wr mem
Cisco Reload Slot Command Linux
Step 2:
Cisco Reload Slot Command Cmd
Schedule a reload in 5-10 minutes (depending on how much time you need).
CiscoRouter# reload in 5
Step 3:
Perform the required configuration changes on the Cisco device (e.g IP change, ACL changes etc).
Reload Cisco Router
Step 4:
If the configuration changes in Step 3 are successful (i.e they didn't kick you out of the device or blocked any traffic etc), then cancel the reload command and save the newly updated configuration.
The following example shows how to immediately reload a Cisco device:
CiscoRouter# reload
Another useful trick to know is to verify first the stored IOS image on the device before reloading:
CiscoRouter# reload /verify
The above will first perform a signature verification and file integrity check on the stored bootflash image file before reloading the appliance. After the verification is done the system will ask you again if you want to reboot the device.
CiscoRouter# reload [text specifying the reason]

Cisco Reload Ospf
Now, if for any reason you made a mistake or the new configuration causes a network problem, the router will reboot itself in 5 minutes thus returning to its previous working configuration before the changes.
