You need to remove the ip address from the physical interface.

I 2nd miller811.

If you are going to use sub interfaces the physical interface cannot have an IP address. use the command "no ip address" in interface configuration mode.

Also make sure the physical interface is turned on.

so it will be like this :

physical interface On .

2nd NO ip on the physical int .

and for the switch , dos it need to be Trunk int ?

Yes the switch needs to be a trunk interface also since you configure Dot1Q vlan trunking on the router.
