Configuring 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.
