Storm Control

Storm control is used to prevent network outages that are caused by broadcast traffic storms. Storm control enables the switching device to monitor traffic levels and to drop broadcast, multicast, and unknown unicast packets when a specified traffic level?called the storm control level or storm control bandwidth?is exceeded, thus preventing packets from proliferating and degrading the LAN.

Starting in Junos OS Evolved release 26.2R1, supported ACX Series routers also include support for different policer rates per traffic type.
