CRBRIM-W/T
Appendix B: Virtual Configuration Register
To change the configuration register while running the system software, follow
these steps:
1.
Enter the enable command and your password to enter the privileged level, as
follows:
Router>
enable
Password:
Router#
2.
At the privileged-level system prompt (CRBRIM-W/T #), enter the command
configure terminal.
You will be prompted as shown in the following example:
Router#
conf term
Enter configuration commands, one per line.
Edit with DELETE, CTRL/W, and CTRL/U; end with CTRL/Z
3.
To set the contents of the configuration register, enter the config-register
value configuration command where value is a hexadecimal number preceded
by
0x
(see Table B-1), as in the following:
config-register 0xvalue
(The virtual configuration register is stored in nonvolatile memory.)
4.
Exit the configuration mode by entering Ctrl-Z. The new value settings will
be saved to memory; however, the new settings do not take effect until the
system software is reloaded by rebooting the CRBRIM-W/T.
5.
To display the configuration register value currently in effect and the value
that will be used at the next reload, enter the show version EXEC command.
The value will be displayed on the last line of the screen display as in the
example following:
Configuration register is 0x142 (will be 0x102 at next reload)
6.
Reboot the CRBRIM-W/T. The new value takes effect. Configuration register
changes take effect only when the server restarts: such as when you switch the
power off and on or when you issue a reload command from the console.
