Configuring Broadcast Cutoff Rate
This setting affects the throttling of excessive broadcast or unicast
packets with unknown MAC addresses being handled by the switch.
Normally, when these types of packets are received by the switch, they
are forwarded (flooded) to every port on the switch or on a VLAN.
However, if the receiving rate of these packets exceeds the broadcast
cutoff rate, the switch will throttle back or limit the forwarding of these
packets based on the configured Broadcast Cutoff Rate. This mechanism
helps to prevent broadcast storms, a problem often encountered in
Ethernet networks.
To configure the broadcast cutoff rate, do the following:
1. Select Switch Configuration Menu from the Main Menu.
2. Select Broadcast Cutoff Rate, enter the rate value, and press [Enter].
Valid values are in the range from 100 to 500,000 per second. This
rate value is applied to each grouping of 8 ports on the switch. A set-
ting of 500,000 essentially disables this feature.
