Step 4 Enter the config terminal command at the enable prompt to enter configuration mode from the terminal:

Router# config terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#

At the Router(config)# prompt, enter the interface type slot/port command to enter the interface configuration mode:

Router(config)# interface serial slot/port

Router(config-int)#

In either configuration mode, you can now enter any changes to the configuration. Press Ctrl-Z(hold down the Control key while you press Z) or enter end to exit configuration mode and return to the EXEC command interpreter.

Step 5 Save your settings to NVRAM. (See the “Saving the Running Configuration to NVRAM” section on page 3-21.) If you do not save the configuration settings you created in the router using configuration mode and the setup facility, your configuration will be lost th enext time yuou load the router.

Your router is now minimally configured and will boot with the configuration you have entered. To see a list of the configuration commands available to you, enter ? at the prompt while in configuration mode.

Saving the Running Configuration to NVRAM

To store the configuration or changes to your startup configuration in NVRAM, enter the copy running-configstartup-configcommand at the Router# prompt:

Router# copy running-config startup-config

Using this command saves the configuration settings that you created in the router using configuration mode and the setup facility. If you fail to do this, your configuration will be lost the next time you reload the router.

Checking the Running Configuration Settings

To check the value of the settings you have entered, enter the show running-configcommand at the

Router# prompt:

Router# show running-config

To review changes you make to the configuration, use the EXEC mode show startup-configcommand to display the information stored in NVRAM.
