Layer 2 Ethernet interface commands
broadcast-suppression
Use broadcast-suppression to enable broadcast suppression and set the broadcast suppression
threshold.
Use undo broadcast-suppression to restore the default.
Syntax
broadcast-suppression { ratio | pps max-pps }
undo broadcast-suppression
Default
Ethernet interfaces do not suppress broadcast traffic.

Predefined user roles

Parameters
ratio: Sets the broadcast suppression threshold as a percentage of the maximum interface rate. The value
range for this argument is 0 to 100. The smaller the percentage, the less broadcast traffic is allowed to
pass through.
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 0 to 1.4881 × the maximum interface rate.
For example, the value range for this argument is 0 to 1488100 on a GE interface.
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, the device might convert the configured value into
a multiple of a certain step supported by the chip. As a result, the actual suppression threshold might 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 1488100 pps on GigabitEthernet 2/1/1.
