Configuring the Interfaces
Step 5 Reenable the interfaces using the no shutdown command. (See the “Shutting Down an Interface”
section on page 4-2 .)
Step 6 Configure all additional line card interfaces as required.
Step 7 After including all of the configuration subcommands to complete your configuration, press
Ctrl-Z—hold down the Control key while you press Z—or enter end or exit to exit configuration mode
and return to the EXEC command interpreter prompt.
Step 8 Write the new configuration to NVRAM as follows
Router# copy running-config startupup-config
