Configuring the network interfaces

Last Updated : Jan 29, 2024 |

About this task

Before you install and configure the Avaya SBC software, you must configure the network interfaces on Azure as follows:

  • For an EMS+SBC deployment – Four network interfaces (M1, A1, B1, M2)

  • For all other deployments, including HA – Six network interfaces (M1, A1, B1, M2, A2, B2)

By default, Azure creates only the one M1 interface automatically, so you have to manually create the rest of the interfaces required by your deployment.

Important:

You must verify that none of the network interfaces have already been assigned prior to configuring them for use with Avaya SBC. If you have not verified this before you configure the network interfaces, you might need to follow a special procedure to detach and then attach the network interfaces. For more information, see the following KB article:

Note:

The screen examples shown in this procedure are shown to assist you using the Azure user interface. Your actual screens may differ than those shown here.

Before you begin

Create three different subnets, one each for Avaya SBC Management, Avaya SBC external, and Avaya SBC internal networks.

Procedure

  1. Verify that you can SSH to the Avaya SBC virtual machine from the subnet that is enabled for your system. Use the password Avaya_123 or @V@Y@_123.

    ssh root@<SBC_VM_IP_ADDRESS -p 22

    If there is a problem using SSH, you can use the Serial Console in Azure.

  2. Log on to the Azure Portal using your Azure logon credentials.
  3. In the search box, enter network interfaces and press Enter.

    The system displays the results based on the search.

  4. Select Network interfaces.

    The system displays the Create network interface window.



    The create network interface window.

  5. Do one of the following depending on if you are adding a total of four or six interfaces:
    Important:

    The M1 management network interface was automatically configured when you first created the VM. You do not need to create the M1 network interface again.

    • Add three network interfaces for EMS+SBC in the following order: SBC_A1, SBC_B1, and SBC_M2.

    • Add five network interfaces for all other SBC configurations, including HA, in the following order: SBC_A1, SBC_B1, SBC_M2, SBC_A2, and SBC_B2.
