Enabling Storm Control

Storm Control limits 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 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 for 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. By default, Storm Control is enabled on all ports -
broadcast only - with threshold of 3500 kbps. Storm Control is disabled by default.
The Storm Control Page provides fields for configuring broadcast Storm Control.
