Chapter 1 Understanding Interface Numbering and Cisco IOS Software Basics
Understanding Cisco IOS Software Basics
Cisco 3700 Series Routers Voice Interface Numbering
Voice interfaces in Cisco 3725 and Cisco 3745 routers are numbered differently from the WAN interfaces
described in the previous section Voice interfaces are numbered as follows:
chassis slot/voice module slot/voice interface
If a 4-channel voice network module is installed in chassis slot 1, the voice interfaces are:
• 1/0/0—Chassis slot 1/Voice module slot 0/Voice interface 0
• 1/0/1—Chassis slot 1/Voice module slot 0/Voice interface 1
• 1/1/0—Chassis slot 1/Voice module slot 1/Voice interface 0
• 1/1/1—Chassis slot 1/Voice module slot 1/Voice interface 1
Understanding Cisco IOS Software Basics
This section describes what you need to know about the Cisco IOS software before you configure the
router using the command-line interface (CLI). This chapter includes the following:
• Getting Help, page 1-13
• Understanding Command Modes, page 1-14
• Undoing a Command or Feature, page 1-15
• Saving Configuration Changes, page 1-15
• Where to Go Next, page 1-15
Understanding these concepts will save time as you begin to use the CLI. 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 Cisco IOS software, proceed to Chapter 2, “Using the Setup Command
Facility.”
Getting Help
Use the question mark (?) and arrow keys to help you enter commands:
• For a list of available commands, enter a question mark:
Router> ?
• To complete a command, enter a few known characters followed by a question mark (with no space):
Router> s?
• For a list of command variables, enter the command followed by a space and a question mark:
Router> show ?
• To redisplay a command you previously entered, press the up arrow key. You can continue to press
the up arrow key for more commands.
