Traffic Control

Use the Traffic Control Setting window to enable or disable storm control and adjust the threshold for multicast and
broadcast storms, as well as DLF (Destination Look Up Failure). Traffic control settings are applied to individual Switch
modules. To view this window, click Configuration > Traffic Control.
Figure 4- 7. Traffic Control Setting window
Traffic or storm control is used to stop broadcast, multicast or ARP request storms that may result when a loop is created.
The Destination Lookup Failure control is a method of shutting down a loop when a storm is formed because a MAC
address cannot be located in the Switch's forwarding database and it must send a packet to all ports or all ports on a
VLAN.
To configure Traffic Control, select the Unit (Unit ID of a Switch in a Switch stack − 15 for a Switch in standalone mode)
you want to configure. Broadcast Storm, Multicast Storm and Destination Lookup Failure may be Enabled or
Disabled. The Threshold value is the upper threshold at which the specified traffic control is switched on. This is the
number of Broadcast, Multicast or DLF packets, in Kbps, received by the Switch that will trigger the storm traffic control
measures. The Threshold value can be set from 0 to 255 packets. The default setting is 128.
