Using the Command-Line
Interface
This chapter describes what you need to know about the Cisco IOS software (the software
that runs the ATM switch router) before you begin to configure it, and includes the
following sections:
• Getting Help
• Understanding Command Modes
• Understanding Interface Numbering
• Undoing a Command or Feature
• Displaying the Configuration
• Saving Configuration Changes
Understanding these concepts will save you time later on. If you have never used the
Cisco IOS software or need a refresher, take a few minutes to read this chapter before you
proceed to the next chapter.
If you are already familiar with the CiscoIOS software, skip this chapter and proceed to the
next chapter, “Getting Started.”
Note This document assumes you have already connected all necessary external devices
to the ATM switch router and configured your PC terminal emulation program for
9600baud, 8 data bits, no parity, and 2 stop bits.
