Enabling Storm Control
A Broadcast Storm is a result of an excessive amount of broadcast messages simultaneously
transmitted across a network by a single port. Forwarded message responses are loaded onto
the network, straining network resources or causing the network to time out.
Storm Control is enabled for all fast Ethernet ports or for Giga ports by defining the packet
type and the rate the packets are transmitted. Ports can also be grouped to provide Storm
protection for the entire group.
The system measures the incoming Broadcast, Multicast, and Unknown frame rate
separately on each port, and discards frames when the rate exceeds a user-defined rate.
The Storm Control page allows network managers to enable and configure Storm Control.
To open the Storm Control page :
• Click Switch > Ports > Storm Control in the Tree View to open the Storm Control
page.
Storm Control Page
The Storm Control page contains the following fields:
• Interface—Indicates the interface on which storm control is being configured.
