CAUTION:
Use this function with caution, because it might consume a large amount of system resources.
After you enable subinterface rate statistics collection on an Ethernet interface, the device periodically
refreshes the rate statistics on the subinterfaces of this Ethernet interface. You can use the display
interface command to view the rate statistics.
To enable subinterface rate statistics collection on an Ethernet interface:

1074BConfiguring storm suppression
You can use the storm suppression function to limit the size of a particular type of traffic (broadcast,
multicast, or unknown unicast traffic) that can be received on a per-interface basis in Ethernet interface
view.
In interface view, you set the maximum size of broadcast, multicast or unknown unicast traffic allowed to
be received on an interface. When the broadcast, multicast, or unknown unicast traffic received on the
interface exceeds this threshold, the system discards packets until the traffic drops below this threshold.
