3.8 Port Bandwidth
A Delta switch allows you to configure bandwidth for each port to avoid a network traffic storm.
3.8.1 Storm Control
A traffic storm occurs when incoming packets flood the LAN, which causes the decreasing of the network
performance. The storm control can prevent flooding packets from affecting the network performance. The
Delta switch allows you to configure both storm control for each interface and rate limiting of each interface for
incoming and outgoing traffic.
3.8.1.1 Storm Control Setting
A broadcast storm occurs when a large number of broadcast messages are transmitted from a single interface
across a network at the same time. Forwarding these messages can overload too much network resources or
cause the network timeout.
The Delta switch can measure the incoming packet rate of the broadcast, multicast, and unknown unicast
packets for each interface and discards packets when the rate exceeds the defined value. You can enable
storm control for each interface by a different packet type and define the threshold of the traffic flow.
IMPORTANT :
Make sure that you save the configuration in the Save Configuration
page after you have applied the configuration changes. (Save


Save Configuration) If you do not save the configuration,
then the configuration will be cleared after the switch is rebooted.
