Implementing Additional Configuration and Maintenance Tasks
This section contains information on the following additional configuration, troubleshooting, and
maintenance tasks:
Configuring the Software Configuration Register
The system uses a 16-bit software configuration register, which allows you to set specific system
parameters. Settings for the software configuration register are written into non-volatile random access
memory (NVRAM).
Following are some reasons for changing the software configuration register settings:
Table 9
the boot field, specified as a binary number that consists of bits 0 through 3 of the software configuration
register.
Caution
To avoid confusion and possibly halting the Cisco 12000 Series Router, remember that valid
configuration register settings might be combinations of settings and not just the individual settings
listed in
