Multicast Suppression On The Ws-X4515, Ws-X4014, And Ws-X4013+ Supervisor Engines - Cisco 4500M Software Manual

Chapter 38 Configuring Port-Based Traffic Control
The following example shows how to enable multicast suppression on ports that have broadcast
suppression already enabled:
Switch# configuration terminal
Enter configuration commands, one per line.
Switch(config)# interface fa3/1
Switch(config-if)# storm-control broadcast include multicast
Switch(config-if)# end
Switch#
Multicast Suppression on the WS-X4515, WS-X4014, and WS-X4013+
Supervisor Engines
Hardware does not provide support for multicast suppression on the WS-X4515, WS-X4014, and
WS-X4013+ supervisor engines. One consequence of using software-based broadcast suppression on
these modules is that all incoming data packets are dropped. Irrespective of your selecting to configure
broadcast suppression only, multicast packets are filtered as well on stub and blocking gigabit ports. The
non blocking gigabit ports that do provide broadcast suppression in hardware also do not filter multicast
packets.
