4.7.7 Storm control
A BroadcastStorm is a result of an excessive amount of broadcast messages simultaneously transmitted across a network by a
single port. Forwarded message responses are heaped onto the network, straining network resources or causing the network to
time out.
The system measures the incoming Broadcast and Multicast frame rate separately on each port, and discard frames when the
rate exceeds a user-defined rate.
The Storm Control page provides fields for enabling and configuring Storm Control. The screen in Figure 4-34 appears.
