Storm control

A network traffic storm occurs when packets flood a physical interface, creating excessive traffic and degrading network performance.

If a threshold is reached, the Storm control setting allows an administrator to suppress excessive inbound multicast, broadcast, and destination lookup failure (DLF) packets. The threshold is a user input and is configured in packets per second. If incoming multicast, broadcast, or DLF traffic exceeds the threshold during a polling interval, the offending traffic is blocked until the start of the next polling interval. This threshold protects against broadcast storms causing disruption to Layer 2 networks being propagated further.

The storm control setting is enabled or disabled on the Logical Interconnect Groups and Logical Interconnects screens as part of the Interconnect Settings panel.

NOTE:

Storm control is supported only on physical uplink and downlink ports, not on stacking ports.
