In this section:
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 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 nodes.
Note
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.

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.
clusterComm type = ip
% set system clusterAdmin clusterComm type ip addressContext <addressContext name> ipInterfaceGroup <IPIG name> pktIpVar <metaVariable>
clusterComm 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.
clusterAdmin Parameters
| Parameter | Description |
|---|---|
clusterComm | Defines 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. |
discoveryComm | Defines the communication interface for the node-discovery protocol. |
seedFqdn | FQDN that maps to the seed nodes. |
seedIpAddress | IP addresses of the seed nodes. Not applicable when |
state | The 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.
clusterComm Parameter Descriptions

|---|---|---|
type | N/A | Interface type to use for intra-cluster communication.
|
| type = ip | ||
addressContext | N/A | Address context containing the IP interface group to use for intra-cluster communication. |
ipInterfaceGroup | N/A | <IPIG name> – The name of the IP interface group for intra-cluster communication. |
pktIpVar | 1-255 characters |
|
| type = mgmt | ||
mgmtInterfaceGroup | N/A | The management interface group for intra-cluster VNFC communication.
|
mgmtIpVar | 1-255 characters |
