Description
Configure the storm control level as the percentage of total interface bandwidth used by the combined broadcast, multicast, and unknown unicast traffic streams on an interface. The storm control level is configured as part of the storm control profile. As an example, a 10 Gbps interface with a 10% storm-control bandwidth configuration provides 1Gbps limit on BUM (broadcast, unknown, and multicast) traffic. So rate of BUM traffic can be up to 1Gbps and if the rate exceeds, the BUM packets are dropped.
When you configure storm control level 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 level 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
On EX4300 switches—The storm control level is 80 percent of the available bandwidth used by the combined broadcast, unknown unicast, and multicast traffic streams.
On EX9200 switches—Storm control is not enabled by default.
On MX Series routers—Storm control is not enabled by default.
