Traffic suppression and storm control are security technologies
to control broadcast packets, unknown multicast packets,
and unknown unicast packets and to prevent broadcast storms caused
by these packets.
Context
Traffic suppression limits the traffic by setting a threshold,
and storm control blocks the traffic by shutting down an interface.
Storm Control
Storm control can prevent broadcast storms caused by broadcast, unknown multicast, or unknown unicast packets.
Traffic Suppression
Traffic suppression limits traffic rate on a switch, to prevent broadcast storms caused by broadcast, unknown multicast, or unknown unicast packets.
