Question about UPF TrafficFlowFilter Connection to Ethernet gate

[dekaio]

Hi,

In the current model, the UPF Traffic flow filter is connected only to the pppFilterGate. May I know if connecting the Traffic Flow Filter to the ethernet interface is correct?

Thank you.

The trafficFlowFilter module is the module receiving the packets from the Internet domain (i.e., from the outside of the 5G network domain). In the UPF module, the pppFilterGate is the gate connected to the Internet domain, so that is why the trafficFlowFilter is connected to it.

Thank you. My UPF module is connected to an L2 switch via an Ethgate. In this scenario, is it correct to connect the Eth gate to the trafficFlowFilter?

I think you can do it, yes.
