The 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 You must configure the clusterAdmin clusterComm options on M-SBC clusters in a distributed SBC SWe Cloud deployment. The clusterComm This configuration is visible only for M-SBC clusters and is required must be completed prior to configuring a load balancing service to distribute media request among the media nodes.

Info
titleNote

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

Command Syntax

The following syntax shows the first-level parameters under clusterAdmin. The subsequent options differ depending on the option you specify for type.

Code Block
% set system clusterAdmin
      clusterComm type <ip 
      dataComm     
      discoveryComm 
      seedFqdn     
      seedIpAddress 
      state       | mgmt>

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>
Code Block
titleclusterComm type = mgmt
% set system clusterAdmin clusterComm type mgmt
   	mgmtInterfaceGroup mgmtGroup 
   	mgmtIpVar <metaVariable>

Command Parameters

The following table summarizes the roles of the first-level clusterAdmin parameters. Except for clusterComm, the options are automatically configured when needed. Caption0Table1clusterAdmin

Parameters

ParameterDescriptionclusterCommDefines intra-cluster communications for the M-SBC load balancing service. Available only on M-SBC deployments. See the following table for more detail.dataComm

Defines the communication interface for data traffic.

discoveryCommDefines the communication interface for the node-discovery protocol.seedFqdnFQDN that maps to the seed nodes.

seedIpAddress

IP addresses of the seed nodes. Not applicable when seedFqdn is configured.

stateThe admin state of the cluster (enabled/disabled).

clusterComm Parameter Descriptions 

The following table describes the parameters under clusterAdmin clusterComm you can use to configure intra-cluster communication for an M-SBC deployment.
