S-SBC Cluster Configuration using SBC Configuration Manager

This section describes how to create initial, basic configuration on a signaling SBC (S-SBC) SWe cluster using the SBC Configuration Manager GUI. Although the following procedures use the GUI, you can also make cluster configuration changes using the CLI on the OAM node. Refer to Modifying SBC Cluster Configuration for information on using the CLI and the CLI Reference Guide for information on the available commands.

The configuration shown here is a basic example and focuses on minimum configuration required for a basic call flow and configuration required by cloud-based clusters. As part of a distributed SBC cloud deployment, an S-SBC cluster must be paired with a media (M-SBC) cluster to provide full SBC functionality. Both cluster configurations include a D-SBC signaling port to allow communication between the two clusters. 

In contrast to assigning static values, cloud deployments use metavariables to assign interface values such as IP addresses. The actual values are determined dynamically during instantiation, based on the cloud environment. 

Beyond this minimal configuration, a full deployment would require further configuration and customization based on the intended use and environment, similar to other types of SBC deployments.

Prerequisites

• The S-SBC cluster configuration must be created in the Insight EMS and configured with a Configuration Type of OAM. Refer to Creating an SBC SWe Cluster and SBC SWe Configuration Management Using OAM Nodes.
• The S-SBC cluster, including its OAM nodes, must be instantiated using either VNFM or the Heat template method of deployment. Refer to Instantiating SBC SWe Using a Heat Template or Instantiating SBC SWe on OpenStack using VNFM.  

Accessing the SBC Configuration Manager

Begin the process to initially configure a new S-SBC cluster by accessing the SBC Configuration Manager for the cluster.

1. Log on to the EMS.

2. Click Network → Cluster Management. The Cluster Management / Manage VNFs window opens listing the SBC clusters registered with the EMS.

   
   
3. Click the radio button adjacent to the name of the S-SBC cluster you want to configure. The Details tab for the selected cluster opens. 

4. Click the Configurations tab.

   
   

5. Click Edit Configuration. The SBC Configuration Manager opens in a separate window against the cluster's active OAM node. See the EMA User Guide for information on using the GUI to configure the SBC.

Validating the Meta Variable Table

To validate the values assigned to metavariables during instantiation, review the Meta Variable table by clicking All → System → Meta Variables. The Meta Variable window opens showing the Meta Variable list. In cloud deployments, metavariables are used to assign interface values, such as IP addresses, whose values are configured dynamically during instantiation.

Create an Address Context

Some of the following procedures require that you specify an address context in which to create configuration objects. The following procedures use an example address context named AC2 as a placeholder. In actual practice you can specify your own address context name or use the default address context. The following steps create an address context named AC2. 

1. Click Configuration → System Provisioning → Category: Base Provisioning → Address Context. The Address Context window opens.
2. Click New Address Context. The Create New Address Context window opens.
