Observing System Startup andPerforming a Basic Configuration 4-13
Configuring the Cisco 12008
Using the Setup Facility or the Setup Command
You must consider the following types of parameters during the initial manual
configuration of your router:
•Global (system-wide) parameters
•Network interface (line card) parameters
As noted earlier, you can establish the above parameters using the setup facility (as
presented to you automatically at initial system startup), or you can issue the setup
command at any time at the privileged EXEC prompt (Router#) to activate the setup
facility.
The only observable difference between the configuration script displayed when you use
the setup facility automatically on startup and that displayed when you issue the setup
command is that the latter displays any existing (previously entered) system configuration
defaults within square brackets [ ].
For example, during the configuration of a POS interface by means of the setup facility at
startup (assuming that the interface has not previously been configured), you will see a
display in the following form as you proceed through the script and respond to queries:
Configuring interface POS4/0:
Is this interface in use?: yes
Configure IP on this interface?: yes
No default or current parameters are enclosed within square brackets [ ] in the configuration
dialog in this instance.
Conversely, when you issue the setup command at the privileged EXEC mode prompt
(assuming that the POS interface has been previously configured and you are bein g queried
by the system for changes), you will see a display in the following form:
Configuring interface POS4/0:
Is this interface in use?[yes]: yes
Configure IP on this interface?[yes]: yes
The default or current parameters applicable to the interface are enclosed within square
brackets [ ].
Proceed to the following sections to configure the global and line card interface parameters
for your system.
