Configuring the Router 4-5

Configuring the Router

If the AutoInstall process is successfully completed, continue to Step 3 to write

the conﬁguration data to the multiport serial router’s nonvolatile random-access

memory (NVRAM). If the Autoinstall process is not successfully completed,

contact your system administrator for assistance.

Step 3 At the enable prompt, enter the copy running-conﬁg startup-conﬁg command:

Router# copy running-config startup-config

This command saves the conﬁguration settings that the AutoInstall process

created in the router. If you fail to do this, the conﬁguration is lost the next time

you reload the router.

Using the Setup Facility

If you do not plan to use AutoInstall, do not connect the multiport serial router’s WAN and

(serial) cable to the channel service unit/data service unit (CSU/DSU). This prevents the

router from attempting to run the AutoInstall process. The router attempts to run

AutoInstall whenever you start it if the WAN connection is connected on both ends and the

router does not have a conﬁguration stored in NVRAM. It can take several minutes for the

router to determine that AutoInstall is not set up to a remote TCP/IP host.

Once the router has determined that AutoInstall is not conﬁgured, it defaults to the setup

facility. If the WAN cable is not connected, the router boots from Flash memory and goes

into the setup facility.

Note You can run the setup facility any time from the enable prompt (#) by entering the

setup command.

Conﬁguring the Global Parameters

You use the setup facility to conﬁgure the global parameters, which are used for controlling

system-wide settings. Take the following steps to enter the global parameters:

Step 1 Connect a terminal by following the instructions in the section “Connecting the

Console Terminal and Modem” in the chapter “Installing the Router” and then

boot the router to the user EXEC prompt (Router>).
