Initial Configuration
To display current port configuration information, use the show running-config command. During
power-on, the interface on a new ATM line card is shut down. To enable the interface, you must enter a
no shutdown command in configuration mode. When the ATM line card is enabled (taken out of
shutdown) with no additional configuration commands applied, the default interface configuration file
parameters listed in Table 13 are used.
To enter a no shutdown command for the ATM line card interface or to change the configuration of the
interface, you must enter configuration mode by using the configure privileged EXEC command.
Configuring an Interface
After you verify that the new ATM line card is installed correctly, use the configure command to
configure the new interface. Be prepared with the information that you will need, such as the interface
IP address.
The following procedure is for creating a basic configuration—enabling an interface and specifying IP
routing. You might also need to enter other configuration subcommands, depending on the requirements
for your router configuration.
(For descriptions of configuration subcommands and the configuration options available, refer to the
appropriate software publications in the “Cisco IOS Software Release Requirements” section on page 2.)
