reload
The reload command reboots a Cisco IOS device, typically used to apply configuration changes or recover from a system issue.
reloadWhen to Use This Command
- After modifying the startup configuration and needing to apply changes by rebooting the router or switch.
- When a device becomes unresponsive or has a software issue that requires a restart.
- To schedule a reboot during a maintenance window using the 'reload in' option.
- To cancel a pending reload with the 'reload cancel' command.
Command Examples
Immediate reload with confirmation
reloadSystem configuration has been modified. Save? [yes/no]: yes Proceed with reload? [confirm]
The router prompts to save the running configuration to startup-config before reloading. Answer 'yes' to save, then confirm the reload.
Scheduled reload with a message
reload in 10 Reloading for maintenanceReload scheduled in 10 minutes Proceed with reload? [confirm]
The reload is scheduled for 10 minutes from now. The message 'Reloading for maintenance' will appear in logs. Confirm to start the timer.
Understanding the Output
The reload command does not produce a persistent output; it prompts for confirmation. The key fields are: 'System configuration has been modified. Save?' indicates unsaved changes; answering 'yes' saves the running config to startup-config. 'Proceed with reload?' requires a final confirmation. If using 'reload in', the device displays the scheduled time and waits. Use 'show reload' to view pending reload status. A successful reload results in the device rebooting and eventually returning to the CLI prompt.
CCNA Exam Tips
Remember that 'reload' is a privileged EXEC command; you must be in enable mode.
The 'reload in' option is useful for scheduling reboots during maintenance windows; know the syntax 'reload in [minutes]'.
You can cancel a scheduled reload with 'reload cancel'.
The 'reload at' command is not supported on all platforms; CCNA focuses on 'reload in'.
Common Mistakes
Forgetting to save the running configuration before reloading, causing loss of changes.
Using 'reload' without scheduling when a maintenance window is required, causing unexpected downtime.
Attempting to use 'reload at' without checking platform support.
