Description

Disable storm control for unknown unicast traffic for the specified interface or for all interfaces.

Default

  • On EX2200, EX3200, EX3300, and EX4200 switches—Storm control does not apply to multicast traffic by default. The factory default configuration enables storm control on all interfaces at 80 percent of the available bandwidth used by the combined unknown unicast and broadcast traffic streams. You can selectively disable storm control on broadcast, multicast, or unknown-unicast traffic.

  • On EX4300 switches—The factory default configuration enables storm control on all interfaces at 80 percent of the available bandwidth used by the combined broadcast, multicast, and unknown unicast traffic streams. You can selectively disable storm control on any type of traffic.

  • On EX4500 and EX8200 switches—The factory default configuration enables storm control on all interfaces at 80 percent of the available bandwidth used by the combined broadcast, multicast, and unknown unicast traffic streams. On EX8200 switches, you can selectively disable storm control on registered multicast traffic, on unregistered multicast traffic, or on both types of multicast traffic.

  • On EX6200 switches—Storm control does not apply to multicast traffic by default. The factory default configuration enables storm control on all interfaces at 80 percent of the available bandwidth used by the combined unknown unicast and broadcast traffic streams. You can selectively disable storm control for each type of traffic individually.

  • On EX9200 switches—Storm control is not enabled by default.

  • MX Series routers—Storm control is not enabled by default.
