Storm-Control Commands
This section describes commands you use to configure storm control and view storm control
configuration information. A traffic storm is a condition that occurs when incoming packets
flood the LAN, which creates performance degradation in the network. The storm control
feature protects against this condition.
configuration information. A traffic storm is a condition that occurs when incoming packets
flood the LAN, which creates performance degradation in the network. The storm control
feature protects against this condition.
The switch provides broadcast, multicast, and unicast story recovery for individual interfaces.
Unicast storm control protects against traffic whose MAC addresses are not known by the
system. For broadcast, multicast, and unicast storm control, if the rate of traffic ingressing on
an interface increases beyond the configured threshold for that type, the traffic is dropped.
Unicast storm control protects against traffic whose MAC addresses are not known by the
system. For broadcast, multicast, and unicast storm control, if the rate of traffic ingressing on
an interface increases beyond the configured threshold for that type, the traffic is dropped.
To configure storm control, you can enable the feature for all interfaces or for individual
interfaces, and you can set the threshold (storm-control level), beyond which the broadcast,
multicast, or unicast traffic is 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.

multicast, or unicast traffic is 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
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 (without 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.)
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 percent, this is
converted to ~25000 pps, and this pps limit is set in forwarding plane
(hardware). You get the approximate desired output when 512 bytes
packets are used.
