Reference Information
Software Configuration Register Settings
Settings for the 16-bit software configuration register are written into the NVRAM. Following are some
reasons for changing the software configuration register settings:
To select a boot source and default boot filename
To enable or disable the Break function
Note The Break function (software configuration register bit 8) when enabled allows you to send a Break
signal to the router during a system (re)boot. This stops the boot process and places the router into ROM
monitor mode. You can activate the Break function by using a dedicated Break key function on the
keyboard, or by entering the Ctrl-[ (left square bracket) key combination.
To control broadcast addresses
To set the console terminal baud rate
To load operating software from Flash memory card or Flash Disk
To enable booting from a Trivial File Transfer Protocol (TFTP) server
