As an alternative to using the default management interface, the SBC supports using an IP address (IPv4 or IPv6) from a packet interface (pkt0 or pkt1) for intra-cluster Virtual Network Function Component (VNFC) communication in distributed SBC (D-SBC) deployments. 

The SBC uses UDP port number 3057 for intra-cluster VNFC communication. Therefore, when using a packet interface, you must set the parameter baseUdpPort to a value higher than 3057 to avoid a conflict.

Perform the following steps:

1. Setting the Base UDP Port Value
2. Configuring Intra-Cluster VNFC Communication Through Packet Ports
3. Configuring Intra-Cluster VNFC Communication Through Packet Ports
4. Configuring Intra-Cluster VNFC Communication Through Packet Ports
5. Configuring Intra-Cluster VNFC Communication Through Packet Ports

Setting the Base UDP Port Value

To set the value of the parameter baseUdpPort to more than 3057, execute the following command:

set system media mediaPortRange baseUdpPort 3060

Configuring the Intra-cluster VNFC Interface

To Configure the use a packet interface for intra-cluster VNFC communication by setting , set the parameter type to type, execute the following commands ip, and specify a packet interface IP Interface Group and metavariable, as in the following examples:

IPv6 address:

set system clusterAdmin clusterComm type ip addressContext default ipInterfaceGroup LIG2 pktIpVar IF3.IPV6  
commit

IPv4 address:

set system clusterAdmin clusterComm type ip addressContext default ipInterfaceGroup LIG2 pktIpVar IF3.IPV4  
commit

To Configure the use a management interface for intra-cluster VNFC communication by setting , set the parameter type to mgmt, execute , and specify a management interface IP Interface Group and metavariable, as in the following commandsexamples:

IPv6 address:

set system clusterAdmin clusterComm type mgmt addressContext default ipInterfaceGroup LIG2 mgmtIpVar IF0.IPV6  
commit

IPv4 address:

set system clusterAdmin clusterComm type mgmt addressContext default ipInterfaceGroup LIG2 mgmtIpVar IF0.IPV4  
commit

Refer to D-SBC Signaling Port - CLI, Load Balancing Service - CLI,

and DNS Group

To Configuring the parameter loadBalancingService for the Cluster, execute the following command:

set system loadBalancingService groupName mCCluster.dsbcUser01.com
set system loadBalancingService privateIpInterfaceGroupName LIG2 
commit

To configure the parameter dsbcSigPort or DFE port for the cluster, execute the following command:

set system dsbc dsbcSigPort ipInterfaceGroup LIG2 ipVarV4 IF3.IPV4 state enabled mode inService
commit

To configure the parameter dnsGroup for the cluster, execute the following command:
