a “level”) disables that form of storm-control but maintains the configured “level” (to be active the next
time that form of storm-control is enabled.)
Note
The actual rate of ingress trac required to activate storm-control is based on the size of
incoming packets and the hard-coded average packet size of 512 bytes - used to calculate a
packet-per-second (pps) rate - as the forwarding-plane requires pps versus an absolute rate
kbps. For example, if the configured limit is 10%, this is converted to ~25000 pps, and this pps
limit is set in forwarding plane (hardware). You get the approximate desired output when
512bytes packets are used.
storm-control broadcast
Use this command to enable broadcast storm recovery mode for all interfaces (Global Config mode) or
one or more interfaces (Interface Config mode). If the mode is enabled, broadcast storm recovery is
active and, if the rate of L2 broadcast trac ingressing on an interface increases beyond the configured
threshold, the trac will be dropped. Therefore, the rate of broadcast trac will be limited to the
configured threshold.

storm-control broadcast action
This command configures the broadcast storm recovery action to either shutdown or trap for all
interfaces (Global Config mode) or one or more interfaces (Interface Config mode). If configured to
shutdown, the interface that receives the broadcast packets at a rate above the threshold is
diagnostically disabled. If set to trap, the interface sends trap messages approximately every 30
seconds until broadcast storm control recovers.
