How to select affected interface in Network Link Conditioner

If you do this directly on the device, you could use the "Add a Profile" button and then select the interface you want to use (Wi-Fi or Cell) and then configure the settings you are wanting to use. This can be found under Settings -> Developer -> Network Link Conditioner -> Add a Profile.

The other way would be to restrict the interface on the physical device itself before the Network Link Conditioner profile is applied. For example, turn off Wi-Fi and forget all Wi-Fi networks completely before applying the profile to set the link conditioner against Cell.

Are you talking about an iOS device? I can't find Settings -> Developer -> Network Link Conditioner -> Add a Profile on macOS. (See tags!)

Are you talking about an iOS device?

I was, sorry for the oversight there. Regarding macOS and the Network Link Conditioner, no, I am not aware of any way to select an available interface to use on the system other than Wi-Fi (E.G. Ethernet, Virtual Interface, Loopback etc...). I would open an Enhancement Request here.

Thank you for the quick reply. I'll file an enhancement request as suggested. :-)
