Configuring M-SBC

This page describes how to create the initial, basic configuration on a media SBC (M-SBC) SWe Cloud cluster using the EMS and the SBC Configuration Manager. For more information on how an SBC cluster interacts with the EMS for configuration, refer to Configuring an SBC SWe Cluster using the EMS.

Prior to following these procedures you must have created an SBC SWe cluster in the EMS and instantiated the SBC cluster. Refer to Creating an SBC SWe Cluster in EMS documentation.

Accessing the SBC Configuration Manager

Begin the process to initially configure a new M-SBC cluster by accessing the SBC Configuration Manager on behalf of the cluster.

1. Log on to the EMS as an admin user.

2. Click 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 M-SBC cluster you want to configure. The Details tab for the selected cluster opens. 

4. Click the Configurations tab. 

   Cluster Configurations Tab

   

5. Click Create Candidate Configuration. 

   Cluster Configurations Tab - Create Candidate Configuration

   

6. Ensure the option selected for Create Candidate Configuration from is Head End. This is the default.

7. Click Load Editor. The SBC Configuration Manager opens against the node the EMS selects as the Head End node for the cluster. A Head End node must be active, online, and registered with the EMS. Later, when you save the configuration, the EMS will push the configuration to other nodes in the cluster.

Configure the SBC using the SBC Configuration Manager

Complete the following procedures to configure 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 an IP interface group and an IP Interface, see Create IP Interface Groups and IP Interfaces.

4. To create Static Route, see Create a Static Route.
5. To create D-SBC SigPort, see Create the D-SBC Sig Port.
6. To create DNS group and DNS server, see Create a DNS Group and a DNS Server.
7. To create an NTP server, see Create an NTP Server.

8. To create a Load Balancing service, see Create a Load Balancing Service.
   
   

Validating the Meta Variable Table

To validate the values assigned during instantiation, review the meta variable table, click All > System > Meta Variables. The Meta Variable window opens showing the Meta Variable list.

Meta Variables

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 AC1 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 AC1. 

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 AC1 as the name of the address context (the name must be between 1-23 characters in length). 
4. Click Save.

Create IP Interface Groups and IP Interfaces

Create IP Interface Groups

1. Select Address Context > IP Interface Group. The IP Interface Group window opens.

3. Click New IP Interface Group. The Create New IP Interface Group window opens.

4. Enter an IP interface group name. Example: MLIG1
   

5. Click Save.
