Page History

This page describes how to create the initial, basic configuration on a signaling SBC (S-SBC) SWe Cloud cluster using the EMS and the SBC Configuration Manager. One SBC node within the cluster, referred to as the "Headend" node, is used for creating the configuration, and the EMS is used for distributing the configuration across the cluster. 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 for the S-SBC cluster. Refer to Creating an SBC SWe Cluster in EMS documentation. You must then instantiate the S-SBC cluster. After instantiation, the SBC nodes register with the EMS, but since there is no configuration yet for the cluster, its nodes start with a blank configuration. 

Accessing the SBC Configuration Manager

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

1. cluster you want to configure. The Details tab for the selected cluster opens. 

2. Click the Configurations tab.

1. 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.

2. Click Create. The SBC Configuration Manager opens against the Headend node.

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).

Saving and Activating the Configuration in the Cluster

Once you have completed making configuration changes:

1. Click Save at the top of the SBC Configuration Manager window. A Save confirmation window opens. 

   Caption

   Image Added

2. Click Save and Activate configuration. This copies the configuration from the Headend SBC back to the EMS as the active configuration. This also sets the Headend SBC configuration status as Config-in-sync and all other non-Headend SBCs as Config-out-of-sync. The EMS pushes configuration differences to all of those nodes which are config-out-of-sync unless the nodes are unavailable. 

   Within the Cluster Management / Manage VNFs window, the Cluster Status column for the cluster displays All nodes online and Activation Complete, once the configuration is successfully activated.

   Info
   title Note:
   The EMS performs the reboot of out-of-sync nodes automatically during initial configuration. However, if the nodes lose synchronization after that point, for example if an activation fails, then you must reboot the nodes to trigger a configuration download to bring the nodes back into sync. To reboot a node, use the Reboot Node option on the Nodes tab.
