you can try this

this will stop all broadcast, multicast and braodcast traffic once it
reaches 0% of total bandwidth.

Just assign it to all required interfaces

interface fastethenet 0/1
  storm-control multicast level 0

get the following error message

Enter configuration commands, one per line.  End with CNTL/Z.
DAR_BP1_CORE(config)#int gi3/48
DAR_BP1_CORE(config-if)#storm-control multicast level 0
Command Rejected: Multicast suppression is not supported on Gi3/48

OK.....

add an access-list to block it.

access-list 111 ip deny 224.0.0.0 0.0.0.255 any

assign the access-list to the interfaces.

Hopefuly this works a bit better....

on the interfaces do I apply it on inbound?

ip access-group 111 in

BennooCommented:
in if you want to block inbound multicast
out if you want to block sending multicast

You can add both to an interface

do not forget some routing protocols use multicast to polulate updates and hello packets,
this may effect your network.
