Defining Storm Control
Storm Control enables limiting the amount of Multicast and Broadcast frames accepted and
forwarded by the device. When Layer 2 frames are forwarded, Broadcast and Multicast frames are
flooded to all ports on the relevant VLAN. This occupies bandwidth, and loads all nodes connected
on all ports.
A Broadcast Storm is a result of an excessive amount of broadcast messages simultaneously
transmitted across a network by a single port. Forwarded message responses are heaped onto the
network, straining network resources or causing the network to time out.
Storm Control is enabled per all ports by defining the packet type and the rate the packets are
transmitted. The system measures the incoming Broadcast and Multicast frame rates separately on
each port and discards the frames when the rate exceeds a user-defined rate.
The Storm Control Page
provides fields for configuring Broadcast Storm Control.
