Make sure you make the layer 2 bvlan on the 3550 also , besides that it looks like it should work . Myself I would make the links with this command and let the switches negotiate the trunks.

switchport mode dynamic desirable on the connecting links.

what do you mean? is thay correct to use swithcport mode trunk on both 3550 and 2960 switch?

thanks again

Yes you can use that also or the way I stated , which is "switchport mode dynamic desirable" instead of switchport mode trunk. Either way will work .
