GS752TXS Smart Switch Software Administration Manual
The switch measures the incoming broadcast/multicast/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.
To display the Storm Control page, click Security
 Traffic Control, and then click the Storm
Control link.
To configure storm control settings:
1. 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.
2. From the Ingress Control Mode menu, select the mode of broadcast affected by storm
control.
• Disable. Do not use storm control.
• Unknown Unicast. If the rate of unknown L2 unicast (destination lookup failure)
traffic ingressing on an interface increases beyond the configured threshold, the traffic
will be dropped.
• Multicast. If the rate of L2 multicast traffic ingressing on an interface increases
beyond the configured threshold, the traffic will be dropped.
• Broadcast. If the rate of L2 broadcast traffic ingressing on an interface increases
beyond the configured threshold, the traffic will be dropped.
3. When the selected Ingress Control Mode is an option other than Disable, select Enable or
Disable from the Status menu to specify the administrative status of the mode.
4. In the Threshold field, specify the maximum rate at which unknown packets are forwarded.
The range is a percent of the total threshold between 0–100%. The default is 5%.
