Abstract
In an example embodiment, there is disclosed herein an apparatus comprising an ingress interface, an egress interface, and a storm controller coupled to the ingress interface and the egress interface. The storm controller is operable to determine whether to forward packets for a traffic flow received at the ingress interface to the egress interface based on a rate over a time period. The storm controller forwards packets for the traffic flow while the rate exceeds a first threshold and is less than a second threshold while a predefined condition exits. The storm controller limits traffic for the traffic flow to the first threshold while the rate exceeds the first threshold and the predefined condition does not exist.
