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.

Configuration Example

Meta variable Metavariable names are used to retrieve the IP addresses for intra-cluster VNFC communication and either packet or management interface variables can be specified as appropriate. For example, on a cloud media-SBC (M-SBC), the IPv6 address of pkt1 is IF3.IPV6, and the IPv4 address of mgt0 is IF0.IPV4. The following examples show use of both packet and management interfaces.
