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