Hello Hariharan,
how is it configured the interface fas0/18?
is it a routed port or a switch port?
this kinf of QoS features are available on routers but C3550 looks like missing these features
Hope to help

You may try these interface commands:
storm-control unicast level
Or
storm-control broadcast level
