Out of Band Management in System Manager

Last Updated : Oct 25, 2021 |

Out of Band Management is two physically or logically separated network connections or both that connects to a private management network of the customer. The network connection provides secure management and administration of Avaya products. With Out of Band Management, you can separate the management network and data network traffic to System Manager.

System Manager provides the following network interfaces:

  • The regular eth0 interface that was present in releases earlier than System Manager Release 10.2.x, is called the Management interface or Out of Band Management interface. The IP address is called as the Management IP address. The Management interface is mandatory for configuration.

    The following are the examples of System Manager Management network traffic:

    • Database replication with Session Manager

    • Element management. For example, Session Manager, Communication Manager, and Avaya Breeze® platform.

    • User management

    • Solution deployment, upgrades, and software patch install

  • If Out of Band Management is enabled, then the public interface is configured with Public IP address and used for the nonmanagement traffic. This is an optional configuration.

    The following are the examples of System Manager nonmanagement or public network traffic:

    • End-user self-provisioning

    • Client devices getting certificates through SCEP

    • Tenant Management

Out of Band Management configuration persists across System Manager upgrades, updates, and restarts.

For configuring Out of Band Management in System Manager, System Manager must be deployed on an Avaya Solutions Platform 130 host that is configured with Out of Band Management. To configure Out of Band Management on Avaya Solutions Platform 130, see Installing the Avaya Solutions Platform 130 Series.

Note:

Once OOBM is enabled on System Manager, public interface eth1 is no longer reachable using ping command from other systems that are present in a public network. However, System Manager can reach other systems on a public interface.

Out of Band Management in a Geographic Redundancy setup

When you configure Geographic Redundancy, provide Management network details only. Validation fails if you configure Geographic Redundancy with Public network details. In Geographic Redundancy setup, you do not disable or enable Out of Band Management on both primary and secondary System Manager virtual machine. You can enable Out of Band Management on the primary System Manager virtual machine and disable Out of Band Management on the secondary System Manager virtual machine, and vice versa.

Restoring System Manager backup

While restoring backup on System Manager with different Out of Band Management network details, the restore operation fails at validation phase.

Tenant Management on Out of Band Management-enabled System Manager

By default, the Multi Tenancy feature is disabled on System Manager when Out of Band Management is enabled. You must enable Multi Tenancy on Out of Band Management-enabled System Manager for the Tenant Management administrator to manage tenant users.
