Hello @thirumg3 

Please do [show interface status] on your switch and please share the output

Also do [show interface trunk] ont that switch.

Thanks.

. you must assign ip address to the Vlan not to the interface

I Think your configuration is not fully configured , You must connect  switch interface FastEthernet0/1 to router interface(inside interface) and  remove switchport mode trunk form all interface except f0/1
