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
