Configure Custom Interface Selection

When the interface IE is not available in the PFCP packets, you can explicitly provide the IP addresses of the network nodes such as SGW-C and SGW-U for identifying and filtering the traffic based on the interface (S1U, S5S8-U and N3). Refer to Interface Filtering and APN/DNN Filtering for more details.
