Initial Configuration Procedures

This section shows how to prepare the Cisco VG202 and Cisco VG204 to perform basic communication functions. You may initially configure your voice gateway by using the Cisco IOS command-line interface (CLI) or by using the setup command facility. To create the initial configuration, the setup command facility prompts you for basic information about your voice gateway and network.

Cisco IOS CLI

To configure the initial voice gateway settings by using Cisco IOS CLI, follow these steps:

Step 1 Set up a console connection to your voice gateway. The following message is displayed:
...
voice gateway con0 is now available
Step 2 Press Return or Enter. The following message is displayed:
Cisco Configuration Professional Express (Cisco CP Express) is installed on this device. 
This feature requires the one-time use of the username "cisco"
with the password "cisco." The default username and password have a privilege level of 15.
Please change these publicly known initial credentials using Cisco CP Express or the Cisco 
IOS CLI.
Here are the Cisco IOS commands.
username <myuser>  privilege 15 secret 0 <mypassword>
no username cisco
Replace <myuser> and <mypassword> with the username and password you want to use.
For more information about Cisco CP please follow the instructions in the QUICK START 
GUIDE for your voice gateway...

User Access Verification
Username:
Step 3 Enter the username cisco, and press Return or Enter. The following prompt is displayed:

Password:

Step 4 Enter the password cisco, and press Return or Enter. The following prompt is displayed:

VG#

A message is displayed 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

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

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

Verify the initial configuration. See the "Verifying and Saving Your Configuration" section.

Setup Command Facility

The setup command facility guides you through the configuration process by prompting you for the specific information that is needed to configure your system. Use the setup command facility to configure a hostname for the voice gateway, to set passwords, and to configure an interface for communication with the management network.

To use the setup command facility, you will need to set up a console connection with the voice gateway and enter the privileged EXEC mode.

To configure the initial voice gateway settings with setup command facility, follow these steps:

Step 1 Set up a console connection to your voice gateway, and enter privileged EXEC mode. For instructions on how to enter privileged EXEC mode, see Step 1 through Step 4 in the "Cisco IOS CLI" section.

Step 2 In privileged EXEC mode, at the prompt, enter setup.
yourname# setup
The following message is displayed:
--- System Configuration Dialog ---
Continue with configuration dialog? [yes/no]:
You are now in setup command facility.

The prompts in the setup command facility 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 3 To proceed using the setup command facility, enter yes:
Continue with configuration dialog? [yes/no]: yes
Step 4 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 5 Enter a hostname for the voice gateway (this example uses VG):
Configuring global parameters:
Enter host name [VG]: VG
Step 6 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 7 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 8 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 9 Respond to the following prompt as appropriate for your network:
Configure SNMP Network Management? [yes]:
    Community string [public]:
A summary of the available interfaces is displayed.

Step 10 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 11 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 configuration is displayed:
The following configuration command script was created:
