Release Information

Statement introduced in Junos OS Release 13.2X50-D10 for EX Series switches.

Statement introduced in Junos OS Release 13.2 for the QFX series.

Statement introduced in Junos OS Release 14.1 for the MX Series routers.

Starting in Junos OS release 17.4R1 for MX Series routers, support for storm control was added for logical systems.


Bind a storm control profile to a given interface.

On switches running ELS software, storm control is enabled by default on all switch interfaces at a level of 80 percent of the combined broadcast and unknown unicast streams. (For the equivalent statement for platforms running non-ELS software, see storm-control.)


If you configure storm control on an aggregated Ethernet interface, the storm-control level is applies to each member interface individually. For example, if the aggregated interface has two members and you configure a storm-control level of 20 kbps, Junos will not detect a storm if one or both of the member interfaces receives traffic at 15 kbps because in neither of these cases does an individual member receive traffic at a rate greater than the configured storm-control level. In this example, Junos detects a storm only if at least one member interface receives traffic at greater than 20 Kbps.
