Release Information

Statement introduced in JUNOS Release 9.1 for EX Series switches.

Option action-shutdown introduced in JUNOS Release 9.6 for EX Series switches.

Description

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

The statements are explained separately.

Default

By default, storm control is enabled on all switch interfaces at a level of 50 percent of the combined broadcast and unknown unicast streams. You can change the storm control level either by configuring it as a bandwidth value for the combined broadcast and unknown unicast traffic streams or by configuring it as a percentage of the combined broadcast and unknown unicast streams.

When you configure storm control bandwidth on an aggregated Ethernet interface, each member of the aggregated Ethernet interface is set with that bandwidth. For example, if you configure 15000 Kbps on ae1, and ae1 has two members, ge-0/0/0 and ge-0/0/1, each member is allowed a bandwidth level of 15000 Kbps. Thus, the storm control bandwidth on ae1 could be up to 30000 Kbps of combined broadcast and unknown unicast traffic streams.
