Sets a threshold value on a bridge port that affects the per-second
forwarding rate of multicast or broadcast traffic that originates on the
segment connected to that port.

Important Considerations
You can use this command to configure the same setting on multiple
ports simultaneously. When you specify multiple port numbers, the
system prompts you to choose the setting and then applies it to all of
the ports.
A value of zero indicates that no limit is configured.
If you want to configure a limit for a trunk, be sure to apply it to the
trunk's anchor port (lowest-numbered port) only. However, be aware
that the limit that you specify applies separately to each link in the
trunk, even though you only enter it once — that is, it is not an
aggregate.
For a larger array of similar options in the CoreBuilder 3500 and 9000
Layer 3 modules, see the Quality of Service (QoS) chapter in this guide
(Chapter 22) and in the appropriate Implementation Guide .
