Use undo multicast-suppression to restore the default. Syntax multicast-suppression { ratio | pps max-pps | kbps max-kbps } undo multicast-suppression Default Ethernet interfaces do not suppress multicast traffic. Views Ethernet interface view Predefined user roles network-admin Parameters ratio: Sets the multicast 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 multicast traffic is allowed to pass through. pps max-pps: Specifies the maximum number of multicast 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 this argument is 1 to 1488100 on a GE interface and 1 to 59524000 on a 40-GE interface. kbps max-kbps: Specifies the maximum number of kilobits of multicast traffic that the Ethernet interface can forward per second. The value range for this argument (in kbps) is 1 to the maximum interface rate. Usage guidelines You can use the multicast storm suppression function to limit the size of multicast traffic on an interface. When the multicast traffic on the interface exceeds this threshold, the system drops packets until the traffic drops below this threshold. Both the storm-constrain and multicast-suppression can suppress multicast storm on a port. The storm-constrain command uses software to suppress traffic, and it affects the device performance to a certain extent. The multicast-suppression command uses the chip to physically suppress multicast traffic, and it has less influence on the device performance than the storm-constrain command. Do not configure the storm constrain command and the multicast-suppression command on a port. Otherwise, the traffic suppression result is not determined. When you configure the suppression threshold in pps or kbps, 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.
