IOS - ROMMON reset command
When using the ROMMON bootstrap program for a router or switch, the reset
command can be used to reboot the device. This command is typically executed after making configuration changes or after recovering the device, such as when:
-
Loading a New IOS Image: After specifying the correct image path or environment variables, you can use the
reset
command to reboot the device and attempt to load the newly defined image. -
Configuration Register Changes: If you’ve modified the configuration register using the
confreg
command (e.g., to bypass the startup configuration for password recovery), you can use thereset
command to restart the device and apply the changes. -
Exiting ROMMON: After completing troubleshooting or recovery tasks, using
reset
will restart the device and attempt to boot into the normal IOS mode.
Syntax:
rommon> reset
- The device will reboot and attempt to load the IOS image specified in the boot environment variables (e.g.,
BOOT
orBOOTLDR
). - If there is no valid image specified or the configuration is incorrect, the router may return to ROMMON mode again.
