[edit ethernet-switching-options                 storm-control                 interface (all | interface-name)]

Description

Configure the storm control level as the bandwidth in kilobits per second of the applicable traffic streams, as follows:

  • On EX2200, EX3200, EX3300, EX4200, and EX6200 switches—Applies to the combined broadcast and unknown unicast streams by default. Storm control does not apply to multicast traffic by default on these switches. If you enable storm control for multicast traffic on a specific interface, the configured bandwidth allocation applies to the combined broadcast, unknown unicast, and multicast traffic on that interface.

  • On EX4500 and EX8200 switches—Applies to the combined broadcast, multicast, and unknown unicast streams.

Note:

When you configure storm control bandwidth on an aggregated Ethernet interface, the storm control level for each member of the aggregated Ethernet interface is set to that bandwidth. For example, if you configure a storm control bandwidth of 15,000 Kbps on ae1, and ae1 has two members, ge-0/0/0 and ge-0/0/1, each member has a storm control level of 15,000 Kbps. Thus, the storm control level on ae1 allows a traffic rate of up to 30,000 Kbps of combined broadcast, multicast, and unknown unicast traffic.

Default

If you omit the bandwidth statement when you configure storm control on an interface, the storm control level defaults to 80 percent of the available bandwidth used by the combined applicable traffic streams. Depending upon the configuration, applicable traffic could include broadcast, unknown unicast, and multicast traffic.

Options

bandwidth—Traffic rate in kilobits per second of the combined applicable traffic streams.

  • Range: 100 through 10,000,000

  • Default: None

Required Privilege Level

system—To view this statement in the configuration.system-control—To add this statement to the configuration.

Release Information

Statement introduced in Junos OS Release 9.5.
