Article 70042: Changing the IP Address of the Avaya AES and ASA

Print

Summary

This article will explain how to change your Avaya Application Enablement Server’s (AES) IP address which also requires a change in the Avaya Site Administration (ASA). Note that these changes will also require network services on the AES to be restarted.

Changing the Avaya Site Administration IP Address

To change the IP that ASA will be pointing to you will need to have the ASA software installed on your machine.

Launch the ASA and click on Start Gedi which will prompt you to connect to the phone system. 

After connecting type change node-name ip in the command box. This will bring up the option to change the IP.

Once you change the IP address you can now either press F3 or you can click on the enter button at the top to save your changes.

Changing Avaya Application Enablement Server's IP Address

To change the AES IP address, you will require Secure Shell (SSH) access to your AES server. PuTTY is one such application that provides a SSH client and may be downloaded here: http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

Launch PuTTY and on the main screen enter the AES IP address in the Host Name (or IP Address) text box. Type a name in the Saved Sessions and click Save. You have now created a saved session of your AES machine connection for easier access. 

Click the Open button and your session will start.

Log in with your root account credentials.

Locate and edit the eth0 interface with an editing program, we use Vim as the tool of choice as it's a commonly installed editing tool. To do this type in the following command:  vi /etc/sysconfig/network-scripts/ifcfg-eth0

 
In this file you will see your IP configuration for the eth0 interface. To make any changes you must press the Insert key, navigate using the arrow keys instead of the mouse.

Below is a breakdown of what each field means:

For more information on the options available for this configuration page please consult the following link: http://www.redhat.com/docs/manuals/enterprise/RHEL-3-Manual/ref-guide/s1-networkscripts-interfaces.html

Save your changes after completing the required edits by hitting the Esc key and the semi-colon ":" key, then type in "wq", which stands for Write and Quit.

Restart AES

In order to make your changes take effect, you must restart the network services on the AES. To do this, type Service network restart or reboot the whole AES machine by typing reboot.

To check the configuration of the eth0 card you can use this command: ifconfig eth0
