Prior releases supported the use of a dedicated SBC Configurator cluster to configure other SBC SWe clusters. This approach is replaced by using one of the SBC nodes within the cluster, referred to as the "Headend" SBC, to configure the other nodes. While the SBC Configurator currently remains supported for backward compatibility, it will be deprecated in a subsequent release. Beginning with release 7.1, use the Headend SBC configuration model described in this topic.

This section describes how to create

initial, basic configuration

for an integrated SBC (I-SBC) SWe Cloud 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 active node on the cluster. Refer to Accessing Configuration Interfaces for SBC SWe Clusters 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. For example, 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 I-SBC cluster configuration must be created in the Insight EMS and configured with a Configuration Type of Direct Single

• . Refer to Creating an SBC SWe Cluster

•  and SBC SWe Configuration Management in Direct Single Mode.
• The I-SBC cluster

• 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 I-SBC cluster by accessing the SBC Configuration Manager on behalf of 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.

4. Click the Configurations tab.

5. Ensure the option selected for Create Candidate Configuration From is Headend. This is the default. A Headend node must be active, online, and registered with the EMS.

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

Configure the SBC using the SBC Configuration Manager

Use the following procedures and examples to configure basic I-SBC parameters using the SBC Configuration Manager.

1. To validate the meta variable table, see Validating the Meta Variable Table.
2. To create an address context, see Create an Address Context.

3. To create IP interface groupa and IP interfaces, see Creating IP Interface Groups and IP Interfaces.

4. To create a static route, see Create a Static Route.
5. To create a DNS group and a DNS server, see Create a DNS Group and a DNS Server.
6. To create a NTP server, see Create an NTP Server.
7. To create zones, see Create Zones.
8. To create SIP signaling ports, see Create SIP Signaling Ports.
9. To create SIP trunk groups, see Create SIP Trunk Groups.
10. To create a remote policy server, see Configuring a Remote Policy Server.
11. To create a load balancing service, see Create a Load Balancing Service.

Validating the Meta Variable Table

To validate the values assigned to metavariables during instantiation, review the meta variable table, click All > System > Meta Variables. 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.

AddressContext AddressContext

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.
3. Enter AC2 as the name of the address context (the name must be between 1-23 characters in length). 
4. Click Save.
