Configure CPN-UPN Communication solution using CLI

CPN-UPN Communication enables traffic management based on Radio Access Network (RAN) and Network Slice attributes in the Standalone User Plane Node (UPN). This feature allows you to enable flow sampling and forward listing based on the RAN attributes and flow sampling based on the Network Slice attributes. This is achieved by establishing communication between GigaSMART 5G CUPS (CPN) and the Standalone UPN .
For more details regarding CPN-UPN communication topology, flow sample map rules, and forward list map rules, refer to CPN-UPN Communication for Support of RAN and Network Slice Attributes.

The below topology explains the 4G CPN & UPN Profile configuration.

The following configuration example explains the configuration flow for 4G CPN (when one 4G CPN communicates with one UPN).
