Chapter 4 System Startup and Basic System Configuration
Cisco IOS User Interface
The following example shows how to configure an ATM line card to use IP.
Configuring interface parameters:
Configuring interface ATM1/0:
Is this interface in use?: yes
Configure IP on this interface?: yes
IP address for this interface: 1.1.1.2
Number of bits in subnet field: 0
Class A network is 1.0.0.0, 0 subnet bits; mask is 255.0.0.0
After you have manually configured the network interface parameters, the RP and line card interfaces are available for limited use.
•To modify the currently saved configuration information, you can enter the setup command at the privileged EXEC mode prompt (Milo#) at any time to start another system configuration dialog session.
•To perform more complex configuration tasks, you can enter the configure terminal command at the privileged EXEC mode prompt (Milo#), which invokes global configuration mode [Milo(config)#]. See the “Using Global Configuration Mode” section on page

The show version command displays the Cisco IOS software version number as well as other information, including the hardware installed in the system, the names and sources of system image files, and the contents of the software configuration register.
