Traffic Control
Use the Traffic Control menu 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 the following window, click
Configuration > Traffic Control :
Figure 6- 38. Traffic Control Settings and Traffic Control Table window
To configure Traffic Control , first select the Switch’s Unit ID number from the pull down menu and then a group of ports
by using the Group pull down menu. Finally, enable or disable the Broadcast Storm , Multicast Storm and Destination
Unknown using their corresponding pull-down menus.
The purpose of this window is to limit too many broadcast, multicast or unknown unicast packets folding the network.
Each port has a counter that tracks the number of broadcast packets received per second, and this counter is cleared once
every second. If the broadcast, multicast or unknown unicast storm control is enabled, the port will discard all broadcast,
multicast or unknown unicast packets received when the counter exceeds or equals the Threshold specified.
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 Kpps (kilo packets per second), received by the Switch that will trigger the storm
traffic control measures. The
Threshold value can be set from 0 to 255 kilo packets per second. The default setting is 128.
The settings of each port may be viewed in the Traffic Control Table in the same window. Click Apply to implement
changes made.
