Cisco Systems 7600 manual Setting the Boot Field Bits in the Software Configuration Register, 2-25

Chapter 2 Basic MSFC Software Configuration

Performing Other Configuration Tasks

Step 4 Exit the global configuration mode by pressing Ctrl-Zor entering the end command:

Router(config)# config-register 0xvalue

Router(config)# end

Router#

The new contents of the software configuration register are saved to NVRAM. These new settings do not take effect until you reload the system or reboot the router.

Step 5 To display the software configuration register setting that is currently in effect as a result of Step 3 (and which will be used at the next reboot of the router), enter the show version command at the privileged EXEC mode prompt:

Router# show version

.

.

.

#Configuration register is 0x141 (will be 0x102 at next reload)

The last line of the display shows both the current configuration register setting and the new setting that will take effect when the system is reloaded or rebooted.

Step 6 Save the software configuration register setting, as described in the “Saving the Running Configuration Settings to NVRAM” section on page 2-19 .

Step 7 Reboot the router.

The software configuration register setting takes effect only after you reload the system, such as when you enter the reload command from the console or reboot the router.

This completes the procedure for changing the contents of the software configuration register. You can set the boot field to enable any desired manual or automatic boot function.

Setting the Boot Field Bits in the Software Configuration Register

The four low-order bits in the software configuration register (bits 3, 2, 1, and 0) comprise the boot field. This field specifies a number in binary form.
