Performing the Initial Configuration

You initially configure your voice gateway by using the Cisco IOS CLI. Then you use the setup command which guides you through the configuration process by prompting you for the specific information that is needed to configure your system. After creating the initial configuration file, you can use the Cisco IOS CLI to perform further configuration.

Password:
 
   

Step 4 Enter the password cisco, and press Return or Enter.

The system displays the following prompt:

VG#
 
   

The system displays a message that is similar to the first warning message. The message directs you to change the username and password.

You are now in privileged EXEC mode.


Note You must change the username and password before you log off the voice gateway. You cannot use the username cisco or password cisco after you log off from this session.


Step 5 To change the username and password, enter the following at the prompt:

username username privilege 15 secret 0 password

Where username and password are the username and password that you wish to use.

Step 6 Use the copy running-config startup-config command at the privileged EXEC mode prompt (VG#) to save the configuration to NVRAM.


Using the setup Command to Configure the Voice Gateway

Before You Begin

Perform the procedure in the "Using the Cisco IOS CLI to Configure the Voice Gateway" section.

Procedure


Step 1 In privileged EXEC mode, at the prompt, enter setup.

yourname# setup
 
   

The system displays the following message:

--- System Configuration Dialog ---
 
   
Continue with configuration dialog? [yes/no]:
 
   

You are now in the setup command facility.

The prompts in the setup command vary, depending on your voice gateway model, on the installed interface modules, and on the software image. The following steps and the user entries (in bold) are shown as examples only.


Note If you make a mistake while using the setup command facility, you can exit and run the setup command facility again. Press Ctrl-C, and enter the setup command at the privileged EXEC mode prompt (VG#).


Step 2 To proceed using the setup command, enter yes:

Continue with configuration dialog? [yes/no]: yes
 
   

Step 3 When the following messages appear, enter yes to enter basic management setup:

At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
 
   
Default settings are in square brackets '[]'.
 
   
Basic management setup configures only enough connectivity
for management of the system, extended setup will ask you
to configure each interface on the system
 
   
Would you like to enter basic management setup? [yes/no]: yes
 
   

Step 4 Enter a hostname for the voice gateway.

Configuring global parameters:
Enter host name [VG]: VG
 
   

Step 5 Enter an enable secret password. This password is encrypted (more secure) and cannot be seen when viewing the configuration.

The enable secret is a password used to protect access to
privileged EXEC and configuration modes. This password, after
entered, becomes encrypted in the configuration.
Enter enable secret: xxxxxx
 
   

Step 6 Enter an enable password that is different from the enable secret password. This password is not encrypted (less secure) and can be seen when viewing the configuration.

The enable password is used when you do not specify an
enable secret password, with some older software versions, and
some boot images.
Enter enable password: xxxxxx
 
   

Step 7 Enter the virtual terminal password, which prevents unauthenticated access to the voice gateway through ports other than the console port:

The virtual terminal password is used to protect
access to the voice gateway over a network interface.
Enter virtual terminal password: xxxxxx
 
   

Step 8 Respond to the following prompt as appropriate for your network:

Configure SNMP Network Management? [yes]:
    Community string [public]:
 
   

The system displays a summary of the available interfaces.

Step 9 Choose one of the available interfaces for connecting the voice gateway to the management network:

Enter interface name used to connect to the
management network from the above interface summary: fastethernet4
 
   

Step 10 Respond to the following prompts as appropriate for your network:

Configuring interface FastEthernet0/0:
Use the 100 Base-TX (RJ-45) connector? [yes]: yes
Operate in full-duplex mode? [no]: yes
Configure IP on this interface? [yes]: yes
    IP address for this interface: 172.1.2.3
    Subnet mask for this interface [255.255.0.0] : 255.255.0.0
    Class B network is 172.1.0.0, 26 subnet bits; mask is /16
 
   

The system displays the configuration:

The following configuration command script was created:
 
   
hostname VG
enable secret 5 $1$D5P6$PYx41/lQIASK.HcSbfO5q1
enable password xxxxxx
line vty 0 4
password xxxxxx
snmp-server community public
!
no ip routing
!
interface FastEthernet0/0
no shutdown
speed 100
duplex auto
ip address 172.1.2.3 255.255.0.0
!
 
   

Step 11 Respond to the following prompts. Enter 2 to save the initial configuration.

[0] Go to the IOS command prompt without saving this config.
[1] Return back to the setup without saving this config.
[2] Save this configuration to nvram and exit.
 
   
Enter your selection [2]: 2

Verifying and Saving Your Configuration

To verify the configuration and save it in NVRAM so that the configuration remains in effect after you restart the voice gateway, enter the following commands:

 
Command
Purpose

Step 1 

VG# show running-config

Displays the current operating configuration, including any changes you have just made.

Step 2 

VG# show startup-config

Displays the configuration currently stored in NVRAM.

Step 3 

VG# copy running-config startup-config

Writes the current running configuration to NVRAM, where it overwrites the startup configuration and becomes the new startup configuration.

Note If you reboot the Cisco VG202, Cisco VG202XM, Cisco VG204, or Cisco VG204XM voice gateway or turn off the power before you complete this step, you lose the configuration.
