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,
Multicast and Broadcast frames are flooded to all ports on the relevant VLAN. This
occupies bandwidth, and loads all nodes connected on all ports.
Storm Control enables limiting the amount of Multicast, Broadcast, and Unknown
Unicast frames (in SPS208 and SPS 224G4 only) accepted and forwarded by the
device. When Layer 2 frames are forwarded, Multicast, Broadcast, and Unknown
Unicast 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.
