Enabling and Disabling Storm Control (ELS)
This task uses Junos OS with support for the Enhanced Layer 2 Software (ELS) configuration style. If your switching device is an EX Series switch and runs software that does not support ELS, see Understanding Storm Control. If your switching device is an EX Series switch and runs software that does support ELS, see Using the Enhanced Layer 2 Software CLI.
On EX4300 switches, the factory default configuration enables storm control on all Layer 2 switch interfaces. The default storm control level is set to 80 percent of the available bandwidth used by the combined broadcast, multicast, and unknown unicast traffic streams.
Storm control is not enabled by default on ACX7000 Series routers, EX9200 switches, and MX Series routers.
You can customize the storm control level for a specific interface. You specify the storm control level as the traffic rate in kilobits per second (Kbps) of the combined traffic streams or as the percentage of available bandwidth used by the combined traffic streams.
You can selectively disable storm control for broadcast, multicast, or unknown unicast traffic on all interfaces or on a specified interface. You can additionally disable storm control on registered or unregistered multicast traffic.
On ACX7000 Series of devices, storm control is supported only at the physical interface level and cannot be applied for known unicast traffic. To disable or unbind storm control profile on ACX7000 series, you need to remove the storm control profile-name from the physical interface.
In the tasks described in this topic, you use the [edit interfaces interface-name unit 0 family ethernet-switching] hierarchy level to bind the storm control profile for EX Series switches and the [edit
interfaces interface-name unit 0 family bridge] hierarchy level
to bind the storm control profile for MX Series routers. Starting in Junos OS release 17.4R1 for MX Series routers, you can also configure storm control
on logical systems.
Configuring Storm Control
You can configure storm control for a specific interface. The storm control level can be customized by explicitly configuring either the bandwidth level or the bandwidth percentage.
bandwidth-level—Configures the storm control level as the bandwidth in kilobits per second of the combined traffic streams.bandwidth-percentage—Configures the storm control level as a percentage of the available bandwidth used by the combined traffic streams.
You can also configure a limit for burst-size. The burst size extends the function of the bandwidth limit to allow for bursts of
traffic that exceed the configured bandwidth.
To configure storm control:
Create a storm control profile and set the storm control level as the traffic rate in kilobits per second of the combined traffic streams:
content_copy zoom_out_map[edit forwarding-options] user@device# set storm-control-profiles profile-name all bandwidth-level kbps
Note:The name of the storm control profile can contain no more than 127 characters.
Bind the storm control profile to a logical interface:
For EX Series Switches (Enterprise Style Configuration Only):
content_copy zoom_out_map[edit] user@switch# set interfaces interface-name unit 0 family ethernet-switching storm-control profile-name
For MX Series routers:
Enterprise Style Configuration:
content_copy zoom_out_map[edit] user@device# set interfaces interface-name unit 0 family bridge storm-control profile-name
Service Provider Style Configuration: Starting in Junos OS release 18.3R1, you can configure storm control in the Service Provider Style configuration on MX Series devices.
