Cisco 12000 Series Internet Routers are typically delivered from the factory with
a mini-Cisco IOS software boot image in the boot flash and a flash card containing
a suitable working Cisco IOS image. If you need a Cisco IOS upgrade, download
the appropriate Cisco IOS image from Cisco.com.
To configure the software configuration register, follow these steps:
Purpose
Enters privileged EXEC mode.
Enters global configuration mode.
Sets the contents of the software configuration register,
where is a 4-bit hexadecimal number as described
value
in Table 8.
Exits global configuration mode.
Displays the software configuration register value
currently in effect. This is the value that will be used
the next time the router reloads. The value is displayed
on the last line of the display, as in the following
example:
Configuration register is 0x141 (will be 0x102 at
next reload)
Saves the software configuration register settings to
NVRAM.
Reboots the router. Configuration register changes take
effect only after the system reloads.
