Release Information

Statement introduced in Junos OS Release 11.1 for the QFX Series.

Description

Apply storm control to all interfaces or to the specified interfaces.

The statements are explained separately.

Note: The no-multicast option is not supported on QFabric systems.

Default

Storm control is disabled by default. If you enable storm control, the default level is 80 percent of the available bandwidth for ingress traffic on all interfaces. You can change the storm control level by configuring it as a specific bandwidth value.

When you configure storm control bandwidth on an aggregated Ethernet interface, each member of the aggregated interface is assigned that bandwidth. For example, if you configure 7000000 Kbps on aggregated interface ae1, and ae1 has two members, xe-2:0/0/0 and xe-2:0/0/1, each member is allowed a bandwidth level of 7000000 Kbps. Thus, the storm control bandwidth on ae1 could be as much as 14000000 Kbps of combined broadcast and unknown unicast traffic.
