5QI to DSCP mapping for QoS

Q/A
#1

Hello, i have free5gc with UERANSIM deployment that runs on a server connected to a layer-3 Aruba switch. I want to connect 2 UEs and treat the traffic from UE1 different than UE2 (in my Aruba switch based on the DSCP value). For this, i tried to change the 5QI value from the webconsole so that it would be mapped to different DSCP value, but it does not seem to work. Does anyone have any idea how to overcome this issue?

Hi,
You can check the SessionManagementData of UDM, here would store value in DB.
If you want to map different DSCP, you may need to modify UPF.

Now free5gc didn’t support QoS in data plane.
