Hey vasanthmanoharan,

It looks like the 4500 series switch does not support subinterfaces on layer 3 interfaces, if this is what you are attempting.

"A Catalyst 4500 series switch does not support subinterfaces or the encapsulation keyword on Layer 3 Fast Ethernet or Gigabit Ethernet interfaces."

Hope this helps,

Thanks.
