• Broadcast Storm Control – Broadcast storms may occur when a device
on your network is malfunctioning, or if application programs are not
well designed or properly configured. If there is too much broadcast
traffic on your network, performance can be severely degraded or
everything can come to a complete halt. You can protect your network
from broadcast storms by setting a maximum threshold for broadcast
traffic.
Field Attributes
• MAC Table Address Entry Age-Out Time – The time after which a
learned entry is discarded if no new traffic is seen from that address.
(Range: 300-765 seconds; Default: 300 seconds)
• Max bridge transmit delay bound control – Limits the time packets
can be queued in the switch. If enabled, packets queued beyond the
specified time will be dropped. (Range: OFF, 1, 2, 4 seconds;
Default: OFF)
• Broadcast Storm Filter Mode – The percentage of a port’s total
bandwidth used by broadcast traffic. When broadcast traffic rises above
the specified threshold, broadcast packets exceeding that threshold will
then be dropped. (Range: OFF, 5, 10, 15, 20, 25%; Default: OFF)
