Description

Configure storm control on the switch.

Apply storm control to all interfaces or to the specified interfaces on switches running non-ELS software. (For the equivalent statement for switches running ELS software, see storm-control.

The remaining statements are explained separately. See CLI Explorer.

Default

On switches running non-ELS software, storm control is disabled by default on all switch interfaces. If you enable storm control and do not specify a storm control level, the default level is 80 percent of the available bandwidth for ingress traffic.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.
