Enter any changes to the configuration.
Note To see a list of the configuration commands available to you, enter ? at the prompt or press the Help key

Step 2 Specify the IP address. The following example uses an IP address of 10.1.1.50:
Router(config-if)# ip address 10.1.1.50 255.0.0.0
Step 3 Change the default settings or configure other features on the interface as needed. The following
example shows you how to change the clock source to internal (the default is receive clock):
Router(config-if)# clock source internal
(See Table 4-5 for a list of commands used to change the default settings.)
Note For more information on configuring interfaces, refer to the Cisco IOS Interface Configuration
Guide and the Cisco IOS Interface Command Reference publications. See “Related Documentation”
section on page xi for more information.
Step 4 Enable the interface.
Router(config-if)# no shutdown
Step 5 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 6 Save the new configuration to NVRAM as follows:
Router# copy running-config startup-config
[OK]
(See the “Saving the Running Configuration to NVRAM” section on page 4-17. Also see the “Checking
the Interface Configurations” section on page 4-18 for examples of interface configurations.)
Your router is now minimally configured and will boot with the configuration you
have entered.
