Storm-Control Broadcast; Storm-Control Broadcast Level - NETGEAR ProSafe M7100-24X User Manual

multicast, or unicast traffic will be dropped. The Storm-Control feature allows you to limit the
rate of specific types of packets through the switch on a per-port, per-type, basis.
Configuring a storm-control level also enables that form of storm-control. Disabling a
storm-control level (using the "no" version of the command) sets the storm-control level back
to the default value and disables that form of storm-control. Using the "no" version of the
"storm-control" command (not stating 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 traffic 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 a specific interface. If the
mode is enabled, broadcast storm recovery is active and, if the rate of L2 broadcast traffic
ingressing on an interface increases beyond the configured threshold, the traffic will be
dropped. Therefore, the rate of broadcast traffic will be limited to the configured threshold.
