4-3-8-2. Broadcast Storm Filtering
Broadcast storm filtering is used to limit the amount of broadcast traffic on
the network. An excessive amount of broadcast traffic can inhibit data
packets from timely delivery.
The valid threshold values are 5%, 10%, 15%, 20%, 25% and NO. If the
broadcast traffic is greater than the configured value, broadcast packets will
be dropped. The default is NO. The default is set so that no broadcast
packets are ever dropped no matter how many broadcast packets there are
on the network.
4-3-8-3. Max Bridge Transmit Delay Bound
Max bridge transmit delay bound (0,1-4 sec): Limits the packets queuing
time in the switch. If enabled, the packets exceeding the queuing time will
be dropped. Press the Space key to set the time. Valid values are 1sec,
2sec, 4sec and Off. The default is 1 second when this feature is enabled.
This setting does not depend on what values are set in the “Priority
Configuration” menu.
Enable Delay Bound: If this parameter is enabled, the “Max bridge transmit
delay bound” must also be configured. This item allows you to limit queuing
time of the low priority packets in the switch. When the low priority packets
exceed the “Max Delay Time” they will be transmitted. Press the Space key
to enable or disable this function. By default the Enable Delay Bound is set
to OFF.
Max Delay Time: Set the time that low priority packets are queued in the
switch. The valid range is 0 to 255 ms. Since the default is OFF, the Max
Delay Time is 0. This item must be set if “Enable Delay Bound” is
configured.
NOTE: “Max bridge transmit delay bound control” must be enabled before
Max Delay Bound is enabled.
