Storm control is used to stop broadcast, multicast or ARP request storms that may result when a
loop is created. The Destination Look Up 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 port, you want to configure. Broadcast Storm, Multicast
Storm and Unknown Unicast 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 Unknown Unicast packets, in Kbps, received by the switch that will trigger the storm
traffic control measures. The Threshold value can be set from 0 to100000Kbps.
