 supports the system  command Cluster Admin commands control communications among SBC nodes in a cluster configuration. This includes the initial discovery of other member nodes in the cluster as well as communication among the nodes during operation. In general, the clusterAdmin parameters are automatically configured if a deployment requires them and do not need to be changed.

One exception is the clusterAdmin clusterComm configuration required on M-SBC clusters in a distributed SBC SWe Cloud deployment. The clusterComm configuration is visible only for M-SBC clusters and is required prior to configuring a load balancing service to distribute media request among the media nodesclusterAdmin clusterComm to configure intra-cluster VNFC communication interfaces for use with the Load Balancing Service.

Info
titleNote

You must restart the SBC after changing the IP addresses address for intra-cluster VNFC communication.

 

Command Syntax

The CLI syntax for non-Cloud and Cloud configurations is shown below. The parameters that display are dependent upon the clusterComm type setting: ip or mgmt.

SBC SWe Cloud Syntax

clusterComm Syntax (M-SBC Deployments Only)

Intra-cluster communications can be configured to occur on either the management interface (default) or a packet interface. The parameters differ based on the type specification as shown below.

Code Block
titleclusterComm type = ip
% set system clusterAdmin clusterComm type ip
	addressContext <addressContext name>
	ipInterfaceGroup <IPIG name>
	pktIpVar <metaVariable>
	type <ip |mgmt>
Code Block
titleclusterComm type = mgmt
% set system clusterAdmin clusterComm type mgmt
   	mgmtInterfaceGroup mgmtGroup 
   	mgmtIpVar <metaVariable>
	type <ip | mgmt>

Command Parameters

This section details the command parameters in two tables, one each for Cloud and non-Cloud SBC configurations.
