Netgear M7100 - creating a trunk

Hey

I need to created a trunk between HP Proliant switch and this netgear switch.
On the HP its real easy to make a trunk, select each port - tell the port it is a trunk and which trunk group it is part of.

However I dont see any option to do so on the Netgear.
I thought it might be LAGS, but when i added my 4 ports to a LAG it dropped me off my network.

any ideas>>
