Traffic Control
Use the Traffic Control window to enable or disable storm control and adjust the threshold for multicast/broadcast/DLF
(Destination Look Up Failure) storms. Traffic control settings are applied to individual Switch modules. To view the following
window, click Configuration > QOS >Traffic Control.
Figure 7- 43. Storm Control Type Setting window
The purpose of this window is to limit too many broadcast, multicast or unknown unicast packets folding the network. The Storm
Control Type Settings you can choose from are: broadcast, broadcast_multicast, broadcast_dlf, and broadcast_multicast_dlf.
The Threshold value is the upper threshold at which the specified traffic control is Switched on. This is the number of Broadcast,
Broadcast/Multicast, Broadcast/DLF, and Broadcast/Multicast/DLF packets received by the Switch that will trigger the storm
traffic control measures. The Threshold value can be set from 10 to 15000 packets per second. The default setting is 15000. The
settings of each port may be viewed in the Traffic Control Information Table in the same window.
To configure the Storm Control Type Setting, select the desired Storm Control Type from the pull-down menu, select the
threshold from the drop-down menu, and click Apply.
To configure the Traffic Control Setting, select the beginning and ending ports by using the From/To pull-down menu. Now,
change the Traffic control State to Enabled and click Apply.
