Can i use line cards Ports to configure DAD Link between Stack Switches, as i am using my SUP 40Gig's ports for VSL.

yes, you can use a port from a line card.

My apologies. It appears that only the sup ports support DAD. Have a look at table-1 in this link:

You are right, So it means , if i want to configure VSL and DAD I have to use only 10 Gig Ports whereas if i use 40 Gig Ports i can't configure DAD.

Correct. 10Gig ports are fine for DAD and Virtual links. You really don't need 40Gig specialty for DAD.

So, you will be just fine with 10Gig ports.
