Configuring Intra-Cluster VNFC Communication Using Packet Ports

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. 

To use the packet IP interface's UDP ports that are higher than 1023, you must set the baseUdpPort parameter. By default the SBC uses UDP port number 3057 for intra-cluster VNFC communication. Therefore, if you want to use a packet interface for intra-cluster communication, you must set the parameter baseUdpPort to a value higher than 3057. This ensures that the traffic on the 3057 port is not considered media traffic and subsequently dropped as rogue media. 

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 use a packet interface for intra-cluster VNFC communication, set the parameter type to 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 use a management interface for intra-cluster VNFC communication, set the parameter type to mgmt, and specify a management interface IP Interface Group and metavariable, as in the following examples:

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
