GS516TP Gigabit Smart Switches Traffic Control From the Traffic Control menu, you can configure MAC filters, storm control, port security, and protected port settings. The Traffic Control folder contains links to features described in the following sections: • Storm Control • Port Security Interface Configuration • Security MAC Address • Protected Ports Storm Control A broadcast storm is the result of an excessive number of broadcast messages simultaneously transmitted across a network by a single port. Forwarded message responses can overload network resources and cause the network to time out. The switch measures the incoming broadcast, multicast, and unknown Unicast packet rate per port and discards packets when the rate exceeds the defined value. Storm control is enabled per interface, by defining the packet type and the rate at which the packets are transmitted. Storm control is configured as a percent of the maximum port speed, which is 1000 M for all ports.  To configure storm control settings: 1. Select Security > Traffic Control > Storm Control. 2. Select the check box next to the port to configure. Select multiple check boxes to apply the same setting to all selected ports. Select the check box in the heading row to apply the same settings to all ports. 3. From the Status menu, select Enable or Disable to specify the administrative status of the mode. 4. From the Control Mode menu, select the mode of broadcast affected by storm control. • Broadcast Only. If the rate of L2 broadcast traffic ingressing on an interface increases beyond the configured threshold, the traffic is dropped. • Multicast & Broadcast. If the rate of L2 multicast and broadcast traffic ingressing on an interface increases beyond the configured threshold, the traffic is dropped. • Unknown Unicast, Multicast & Broadcast. If the rate of unknown L2 unicast (destination lookup failure), broadcast and multicast traffic ingressing on an interface increases beyond the configured threshold, the traffic is dropped. 5. In the Threshold field, specify the maximum rate at which unknown packets are forwarded. The range is a percentage of the total threshold between 0-100%. The default is 5%. Storm control is configured as a percentage of the maximum port speed. 6. Click APPLY to update the switch with the new settings. 132

Traffic Control

From the Traffic Control menu, you can configure MAC filters, storm control, port security,

and protected port settings.

The Traffic Control folder contains links to features described in the following sections:

•

Storm Control

•

Port Security Interface Configuration

•

Security MAC Address

•

Protected Ports

Storm Control

A broadcast storm is the result of an excessive number of broadcast messages

simultaneously transmitted across a network by a single port. Forwarded message

responses can overload network resources and cause the network to time out.

The switch measures the incoming broadcast, multicast, and unknown Unicast packet rate

per port and discards packets when the rate exceeds the defined value. Storm control is

enabled per interface, by defining the packet type and the rate at which the packets are

transmitted.

Storm control is configured as a percent of the maximum port speed, which is 1000 M for all

ports.



To configure storm control settings:

Select

Security > Traffic Control > Storm Control

Select the check box next to the port to configure. Select multiple check boxes to apply the

same setting to all selected ports. Select the check box in the heading row to apply the same

settings to all ports.

From the Status menu, select Enable or Disable to specify the administrative status of the

mode.

From the Control Mode menu, select the mode of broadcast affected by storm control.

•

Broadcast Only

. If the rate of L2 broadcast traffic ingressing on an interface

increases beyond the configured threshold, the traffic is dropped.

•

Multicast & Broadcast

. If the rate of L2 multicast and broadcast traffic ingressing on

an interface increases beyond the configured threshold, the traffic is dropped.

•

Unknown Unicast, Multicast & Broadcast

. If the rate of unknown L2 unicast

(destination lookup failure), broadcast and multicast traffic ingressing on an interface

increases beyond the configured threshold, the traffic is dropped.

In the Threshold field, specify the maximum rate at which unknown packets are forwarded.

The range is a percentage of the total threshold between 0–100%. The default is 5%. Storm

control is configured as a percentage of the maximum port speed.
