Unicast Packet Storm Blocking on Cat IOS and IOS

Unanswered Question

Does the "Storm Control" feature help in blocking sudden attacks from a specific port?

Scenario:

One person in one classroom in one building coming back to a switch (2948 or 2900XL) is flooding the network with zillion bits per second. He has a virus and doesn’t know he is sending that many packets per second and bringing down the entire network. Can I block this traffic with the “Storm Control” feature at the port level (or even the uplink) so it block the port until it reaches a normal threshold again? These are not broadcasts, but unicast packets. Any suggestions are welcome. Thanks you.

I think it should.

If you have any doubts, test it.

Put one switch to a lab network, connect two PCs to it, set an extremly low threshold for unicast storm control, start some traffic between the PCs and observe if unicasts are dropped or not.
