Start and Configure the System
Start a Basic Configuration
Many privileged-level EXEC commands are used to
set operating parameters. To enter the
privileged-level:
Step 1
Enter the enable command at the EXEC
prompt (>), and then enter a
privileged-level password, as follows:
Router> enable
Password:
Router#
Step 2
Enter the configure terminal command to
enter configuration mode:
Router# configure terminal
Enter configuration commands, one per line.
End with CNTL/Z.
Router(config)#
Step 3
Enter the config-register value
configuration command, where value is a
hexadecimal number preceded by 0x, as in
the following example:
Router(config)# config-register 0x010F
Step 4
Press Ctrl-Z to exit configuration mode.
Step 5
Save the new settings to NVRAM. Enter
the copy running-config startup-config
command.
Note
The new settings do not take effect until the
system software is reloaded by rebooting the router.
Step 6
Enter the show version command to view
the configuration register value currently
in effect. The value is displayed on the last
line of the screen display:
Configuration register is 0x141 (will be 0x101
at next reload)
Step 7
Reboot the router, and then perform a
basic configuration using:
•
AutoInstall (proceed to Step 8)
•
Setup facility (proceed to the “Perform a Basic
Configuration Using Setup” section on page 19)
•
Configuration mode (proceed to the “Perform a
Basic Configuration Using Configuration
Mode” section on page 23)
Note
Configuration register changes take effect
only when the system reloads, such as when you
issue a reload command from the console.
Configure Using AutoInstall
Step 8
Connect to the network using a serial
(WAN) cable to the channel service
unit/data service unit (CSU/DSU).
Step 9
Contact your system administrator to
verify that the TCP/IP host on your
network is preconfigured.
Step 10
Press Ctrl-Z to exit configuration mode.
Step 11
At the # prompt, enter the copy
running-config startup-config command
to save the configuration to NVRAM as
follows:
Hostname# copy running-config startup-config
This completes the procedure for performing a basic
configuration using AutoInstall.
