HP MSM 760 DHCP RELAY

[Dw18ExDVA]

Good day.

I'm using HP MSM 760 controller (v 5.5 firmware). I need to do DHCP Relay.

When I enabled this option in network frame I got that MSM 760 ain't doing this properly.

There is no problem when you're using simple gateway device for relay that don't care about MAC.

But I't a real issue when you are using more complicated devices. MSM don't send client's MAC to server, all requests are marked with controller MAC. That is not right thing that  I should get. 

If anyone can give me a clue it will be great.
