I did like some of the pop crap in the '90s, but I was a kid, and stupid. These kids today and the garbage they listen to. It's disgusting. Now I sound like an old fart. Get off my lawn!

This is exactly what Canopy does. DSCP12/AF is sent over the HP channel. Look at the default DiffServ table and see for yourself. Many managed switches are set up exactly the same way, except they have more queues, and Canopy only has MIR and HP. Well, there's LP CIR, but lets not get into that. ePMP just has "priority" which I assume means priority over everything else. I need a way to correct stupid manufacturer's mistakes (Grandstream being the worst offender). Lots of their devices ALWAYS send SIP packets as DSCP12 and this CANNOT be changed. Or the other one I mentioned, the GXP phones have one DSCP setting and this changes both SIP and RTP. I'm disgusted with their stupidity, but unfortunately it has to be supported because those devices aren't going away. It's totally doable and Cambium could add it by default, saving me time configuring every radio with it. Or just make DiffServ on ePMP work/configure like Canopy. I don't care what's wrong or right. I care about shit working right now and customers not being pissy. So the burden falls on the network as usual. It's always our fault. Sometimes I just don't know how I haven't murdered people. If I drank, it would probably happen. And I'm finding myself agreeing with that one guy Steve every other day now. Stupidity has no limit.
