11.3 Broadcast
Storm Control
The broadcast storm control is used to block the excessive broadcast
packets received during the specified time unit. The valid number
ranges from 1 to 63. The broadcast packet is only checked at the
selected port and the number of broadcast packets is counted in every
time unit.
There are 3 options for the selection of the time unit: 50, 500, or 5000
us as the figure shown above. Once the broadcast storm protection is
enabled, the excessive broadcast packet will be discarded. For those
broadcast packets incoming from the un-selected port, the switch
treats it as the normal traffic.
1.
Threshold: Indicates the number of packets allowed during the
time period based on the selected port bandwidth.
2.
Enable: Select the port to apply the packet number limit to.
3.
Update: Select update to apply the setting.
NOTE:
If function is applied to each port, update must be used
prior to setting a program for the next port. Broadcast packets
incoming from the un-selected ports will be treated as normal
traffic.
