R0106-HP MSR Router Series Interface Command Reference(V7)

39
Parameters
ratio: Sets the unicast suppression threshold as a percentage of the maximum interface rate. The value
range for this argument (in percentage) is 0 to 100. The smaller the percentage, the less unicast traffic is
allowed to pass through.
pps max-pps: Specifies the maximum number of unicast 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 the argument is 0 to 1488100 on a GE interface.
Usage guidelines
You can use the unicast storm suppression function to limit the size of unicast traffic on an interface. When
the unicast traffic on the interface exceeds this threshold, the system discards packets until the unicast
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 unicast storm suppression threshold to 1488100 pps on GigabitEthernet 2/1/1.
