CHAPTER 1
Understanding Interface Numbering and Cisco
IOS Software Basics
This chapter provides an overview of interface numbering in the Cisco VG400 Voice Gateway (VG). This
chapter also describes how to use the Cisco IOS software commands.
This chapter consists of the following major topics:
•Understanding Cisco IOS Software Basics, on page 1
•Upgrading to a New Cisco IOS Release, on page 3
•Where to Go Next, on page 3
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 CLI. Understanding these concepts will save time as you begin to use the commands. If you have
never used 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 the Configuring the Host Name and Password,
on page 5 section.
This chapter includes the following:
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 ?
Cisco VG400 Voice Gateway Software Configuration Guide

• To redisplay a command you previously entered, press the Up Arrow key. You can continue to press the
Up Arrow key for more commands.
Command Modes
The Cisco IOS user interface is divided into different modes. Each command mode permits you to configure
different components on your router. The commands available at any given time depend on which mode you
are currently in. Entering a question mark (?) at the prompt displays a list of commands available for each
command mode. The following table lists the most common command modes.
Table 1: Common Command Modes
Exit MethodRouter Prompt
Displayed
Access MethodCommand Mode
Use the logout command.Router>Log in.User EXEC
To exit to user EXEC mode, use
the disable,exit, or logout
command.
Router#From user EXEC mode, enter
the enable command.
Privileged EXEC
To exit to privileged EXEC mode,
use the exit or end command, or
press Ctrl-Z.
Router (config)#From the privileged EXEC
mode, enter the configure
terminal command.
Global
configuration
To exit to global configuration
mode, use the exit command.
To exit directly to privileged EXEC
mode, press Ctrl-Z.
Router
(config-if)#
From the global configuration
mode, enter the GigabitEthernet
interface command such as,
gigabitethernet0/0.
Interface
configuration
Each command mode restricts you to a subset of commands. If you are having trouble entering a command,
check the prompt, and enter the question mark (?) for a list of available commands. You might be in the wrong
command mode or be using the wrong syntax.
Timesaver
In the following example, notice how the prompt changes after each command, to indicate a new command
mode for Cisco vg400:
Router> enable
Password: <enable password>
Router# configure terminal
Router(config)# interface gigabitEthernet 0/0/0
Router#
%SYS-5-CONFIG_I: Configured from console by console
The last message is normal and does not indicate an error. Press Return to get the Router# prompt.
Press Ctrl-Z in any mode to immediately return to enable mode ( Router# ), instead of entering exit, which
returns you to the previous mode.

Command Modes

Undoing a Command or Feature
If you want to undo a command you entered or disable a feature, enter the keyword no before most commands.
For example, no ip routing.
Saving Configuration Changes
Enter the copy running-config startup-config command to save your configuration changes to nonvolatile
random-access memory (NVRAM). Doing so ensures that the changes are not lost if there is a system reload
or power outage. For example:
Router# copy running-config startup-config
Building configuration...
It might take a minute or two to save the configuration to NVRAM. After the configuration has been saved,
the screen displays the following:
[OK]
Router#
Upgrading to a New Cisco IOS Release
To install or upgrade to a new Cisco IOS release, see How to Update or Upgrade Cisco IOS Software .
Where to Go Next
Now that you have learned some Cisco IOS software basics, you can begin to configure the router using the
CLI.
Remember that:
• You can use the question mark (?) and arrow keys to help you enter commands.
• Each command mode restricts you to a set of commands. If you have difficulty entering a command,
check the prompt and then enter the question mark (?) for a list of available commands. You might be
in the wrong command mode or be using the wrong syntax.
• To disable a feature, enter the keyword no before the command. For example, no ip routing.
• Save your configuration changes to NVRAM so the changes are not lost if there is a system reload or
power outage.
Proceed to Configuring the Host Name and Password, on page 5 to begin configuring the router.

CHAPTER 2
Configuring with the Command-Line Interface
This chapter describes how to use the Cisco IOS software CLI to configure the basic Cisco VG400 analog
functionality.
Follow the procedures described in this chapter to configure the Cisco VG400 Voice Gateway. Note that you
can change the configuration after you have run the setup command facility.
This chapter does not describe every configuration possible—only a small portion of the most commonly
used configuration procedures. For advanced configuration topics, refer to the respective technology
configuration guides.
This chapter consists of the following major topics:
•Configuring the Host Name and Password, on page 5
•Verifying the Host Name and Password, on page 7
•Configuring a Gigabit Ethernet Interfaces, on page 8
•Saving Configuration Changes, on page 9
Configuring the Host Name and Password
One of the first configuration tasks you might want to do is to configure the host name and set an encrypted
password. Configuring a host name allows you to distinguish a router from another. Setting an encrypted
password helps pevent unauthorized configuration changes.

Configuring with the Command-Line Interface
Verifying the Host Name and Password

• You entered the correct password. Passwords are case sensitive.
Configuring a Gigabit Ethernet Interfaces
To configure a Gigabit Ethernet interface, use the configuration software provided with your Cisco VG400
Voice Gateway or network module, if any. Otherwise, for high power and flexibility, use the configuration
mode (manual configuration).
Before you begin, disconnect all the WAN cables from Cisco VG400 to prevent it from running the AutoInstall
process. Cisco VG400 attempts to run AutoInstall whenever you power the Voice Gateway on and there is a
WAN connection on both ends. Cisco VG400 does not have a valid configuration file stored in NVRAM (for
instance, when you add a new interface). It can take several minutes for Cisco VG400 to determine that
AutoInstall is not connected to a remote TCP/IP host.
Note
This section describes a basic configuration, including enabling the interface and specifying IP routing.
Depending on your requirements and the protocols that you plan to route, you might have to enter other
configuration commands.
Before you begin configuring the interfaces, perform the following tasks:
• Connect a console to Cisco VG400.
• Power on Cisco VG400.

CHAPTER 3
Configuring Voice Ports
This chapter explains how to configure voice ports using the commands specific for Cisco VG400 Analog
Voice Gateways and associated service modules.
This chapter contains the following topics:
•Prerequisite, on page 13
•Configuring the Voice Port, on page 13
•Cisco IOS Bulk Configuration, on page 14
Prerequisite
Before you configure voice ports on Cisco VG400 you must establish a working IP network.
Configuring the Voice Port
This section discuss the changes and modifications on the following commands:
loop-length
The loop-length CLI is created to configure the analog FXS voice port. It has the following format:
voice-port x/y/z
[no] loop-length [long | short]
The loop-length CLI has the following characteristics:
• For the Cisco VG400 platform, the default is short loop-length. This command is not applicable to analog
FXS on motherboard slot.
• This command is applicable to all 48 FXS voice ports on SM-D-48FXS-E and the first 4 (0-3) FXS voice
ports on SM-D-72FX like the Cisco VG400 platform.
• The default FXS is short loop-length and long loop-length FXS needs to be configured.
• The first eight voice ports 0/0/0-7 can be configured as long loop (OPX-lite).
• FXS voice ports on VIC 1 (0/1/0 - 0/1/23) will not support long loop. By default, they are short-loop
FXS.
Cisco VG400 Voice Gateway Software Configuration Guide
13

• Shutdown and no shutdown are required on the voice port after loop-length is configured for it totake
effect.
• Because up to 2 ren is supported on long-loop (OPX-lite) FXS, when loop-length long is configured on
the FXS voice port, if its existing ren configuration is greater than 2, it will be changed automatically to
2, a message “The existing ren configuration is changed to 2" is displayed on the console.
•When loop-length short is configured on the FXS voice port, if the voice port has ring dc-offset configured,
the ring dc-offset configuration will be removed. A message “The existing ring dc-offset configuration
is removed” is displayed on the console.
ren
The existing ren CLI under FXS voice port will accept value 1-2 for FXS voice port with loop-length long
configured. For short loop-length analog FXS voice port, ren CLI will accept value 1-5.
ren dc-offset
The existing ring dc-offset CLI is configurable on the long loop-length FXS voice port.
cm-current-enhance
The existing cm-current-enhance CLI is configurable on the long loop-length FXS voice port.
vmwi
The existing vmwi [fsk | dc-voltage] is configurable on all on-board FXS voice ports.
For configuration examples, see Cisco VG400 Configuration Examples.
Cisco IOS Bulk Configuration
An optional bulk-configuration mechanism for voice-port and voice dial peer is available to save on time.
group
The group option is added to dial-peer CLI for dial peer bulk configuration. It has the following formats:
dial-peer group <tag> pots
dial-peer group <tag> pots all stcapp
The second command from the above list will create dial peers on all analog voice ports as stcapp ports by
expanding it to the following three commands:
dial-peer group <tag> pots
service stcapp
port all
The group command is specific for stcapp-controlled analog ports. Therefore, only a subset of dial peer
commands are supported, which are as follows:
1. port
