Which command is used to change the configuration register setting?

The command used to change the configuration register setting in Cisco devices is "config-register." This command allows a network administrator to modify how the router or switch processes the boot sequence and other critical functions.

The configuration register is a 16-bit value that affects the device’s hardware operation. Changing this value can influence the loading of the operating system, how the device enters into ROM monitor mode, or how it manages the startup configuration. For example, a common change to the configuration register is to set it to ignore the startup configuration during boot, which is often used for recovery purposes.

Using the correct syntax "config-register" is essential since Cisco devices are designed to recognize this command specifically. Any deviation from this command name results in an error, emphasizing the need for precision when modifying system settings.
