Configuring the Broadcast/Multicast/Unknown Unicast Storm Suppression Ratio for
an Ethernet Port
You can use the following commands to suppress the broadcast, multicast, and unknown unicast traffic.
In port configuration mode, the suppression ratio indicates the maximum broadcast, multicast, or
unknown unicast traffic that is allowed to pass through a port. When the broadcast, multicast, or
unknown unicast traffic passing the port exceeds the threshold, the system will discard the extra
packets so that the broadcast, multicast, or unknown unicast traffic ratio can drop below the limit to
ensure that the network functions properly.
The storm suppression ratio settings configured for an Ethernet port may get invalid if you configure a
traffic threshold for the port using the storm-constrain command.
Follow these steps to set the broadcast/multicast/unknown unicast storm suppression ratios:

If configured in Ethernet port view, this
feature takes effect on the current port only;
if configured in port group view, this feature
takes effect on all the ports in the port
group.
Configure broadcast storm

{ ratio | pps max-pps }
Optional
By default, all broadcast traffic is allowed to
pass through a port, that is, broadcast
traffic is not suppressed.
Configure multicast storm
suppression ratio multicast-suppression
{ ratio | pps max-pps }
Optional
By default, all multicast traffic is allowed to
pass through a port, that is, multicast traffic
is not suppressed.
