Parameters
ratio: Sets the broadcast suppression threshold as a percentage of the maximum interface rate. The value
range for the argument is 0 to 100. The smaller the percentage, the less broadcast traffic is allowed to
pass through. The argument is always 100. As a result, you cannot suppression broadcast traffic by using
the argument.
pps max-pps: Specifies the maximum number of broadcast packets that the interface can forward per
second. The value range for the max-pps argument (in pps) is 1 to 1.4881 × the maximum interface rate.
For example, the value range for the argument is 1 to 1488100 on a GE interface.
kbps max-kbps: Specifies the maximum number of kilobits of broadcast traffic that the Ethernet interface
can forward per second. The value range for the argument (in kbps) is 1 to the maximum interface rate.
Usage guidelines
You can use the broadcast storm suppression function to limit the size of broadcast traffic on an interface.
When the broadcast traffic on the interface exceeds this threshold, the system drops packets until the
traffic drops below this threshold.
When you configure the suppression threshold in pps or kbps, the device converts the configured value
into a multiple of a certain step (6400 for pps and 50 for kbps) supported by the chip. As a result, the
actual suppression threshold may be different from the configured one. To determine the suppression
threshold that takes effect, see the prompts on the device.
Examples
# Set the broadcast suppression threshold to 10000 kbps on GigabitEthernet 3/0/1.

IMPORTANT:
Fiber ports do not support this command.
Use mdix-mode to configure the Medium Dependent Interface Cross-Over (MDIX) mode of an Ethernet
interface.
