Deploying EMS on a dedicated server using CLI

Last Updated : May 19, 2023 |

About this task

Use this procedure when you want dedicated EMS servers. For EMS, you must deploy at least one EMS server, which is called the Primary EMS. You can optionally deploy a Secondary EMS server.

Caution:

When deploying the Secondary EMS server, verify that the software version of the Secondary EMS server matches the software version of the Primary EMS server. If the software versions do not match, the system will not work properly.

For example, a version mismatch might occur if the Primary EMS server was deployed but the Secondary EMS server was not deployed until a later time. If the Primary EMS server gets a software update before you deploy the Secondary EMS server, a version mismatch occurs.

Before you begin

Verify that the server you are deploying for EMS has the Avaya SBC software installed. To confirm that the primary and secondary EMS servers have the same version of software, do the following steps:

  1. Turn on the primary EMS server.

  2. Wait for the configuration menu to appear.

  3. From the menu, select 4 to go to the shell prompt.

  4. Run the following command: rpm -qa | grep sbce

  5. Repeat these steps on the secondary EMS server.

  6. Compare the software versions. If the versions do not match, you must reinstall the Avaya SBC software on one or both servers so that the same software version is on both EMS servers. If you need to reinstall the Avaya SBC software, see the software installation instructions given earlier in this document.

Procedure

  1. Turn on the system.
  2. Wait for the configuration menu to appear.

    The options are:

    • 1-configure: Command line mode

    • 2-Reboot SBCE

    • 3-Shutdown SBCE

    • 4-SBCE Shell Login

  3. Type 1 for CLI mode.
  4. Depending on the IP address used in your network, type the IP Mode from the following choices and press Enter:

    • IPv4

    • DUAL STACK

    If you are using dual stack for any of the data interfaces, then configure the system with dual stack. The IP Address on Management interface (M1) or (M2) supports only IPv4.address, it does not depend on the type of IP Mode.

  5. Type the Appliance Type as EMS and press Enter:
  6. Type the passphrase in the Network Passphrase field and press Enter.
  7. Type a name for the appliance in the Appliance Name field and press Enter.
  8. Type the installation type for EMS in the Installation Type field from the following choices and press Enter:

    • Primary

    • Secondary

    Caution:

    When deploying the Secondary EMS server, verify that the software version of the Secondary EMS server matches the software version of the Primary EMS server. If the software versions do not match, the system will not work properly.
