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.

% set system clusterAdmin
      clusterComm   
      dataComm     
      discoveryComm 
      seedFqdn     
      seedIpAddress 
      state

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

ParameterDescription
clusterCommDefines 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.
seedFqdn

FQDN that maps to the seed nodes.

seedIpAddress

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

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

ParameterLength/RangeDescription
typeN/A

Interface type to use for intra-cluster communication.

  • ip - to use a packet interface.
  • mgmt (default) - to use the management interface.
type = ip
addressContextN/AAddress context containing the IP interface group to use for intra-cluster communication.
ipInterfaceGroupN/A<IPIG name> – The name of the IP interface group for intra-cluster communication.
pktIpVar1-255 characters

<metaVariable> – The configuration metaVariable that specifies the IP address for intra-cluster communication.

 

type = mgmt
mgmtInterfaceGroupN/A

The management interface group for intra-cluster VNFC communication.

    • mgmtGroup (default)
mgmtIpVar1-255 characters

<metaVariable> – The configuration metaVariable that specifies the IP address for intra-cluster communication. (default = IF0.IPV6)

 

Configuration Examples

To configure packet interface using IPv6 address for VNFC communication in a Cloud M-SBC cluster:

To configure packet interface using IPv4 address for VNFC communication in a Cloud M-SBC cluster:

% set system clusterAdmin clusterComm type ip addressContext default ipInterfaceGroup MLIG2 pktIpVar IF3.IPV4
commit

 

To configure management interface using IPv6 address for VNFC communication in a Cloud M-SBC cluster:

% set system clusterAdmin clusterComm type mgmt mgmtInterfaceGroup mgmtGroup mgmtIpVar IFO.IPV6
commit

 

To configure management interface using IPv4 address for VNFC communication in a Cloud M-SBC cluster:

% set system clusterAdmin clusterComm type mgmt mgmtInterfaceGroup mgmtGroup mgmtIpVar IFO.IPV4
