Storm Control

A traffic storm is a condition that occurs when incoming packets flood the LAN, which creates performance degradation in the network. The Unified Switch’s Storm Control feature protects against this condition.

The Unified Switch provides broadcast, multicast, and unicast storm recovery for individual interfaces or for all 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.

To configure storm control, you’ll enable the feature for all interfaces or for individual interfaces, and you’ll set the threshold (storm control level) beyond which the broadcast, multicast, or unicast traffic will be dropped.

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 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 next time that form of storm-control is enabled).
