Configuring Broadcast Storm Control
Broadcast Storm Control limits the amount of Multicast and Broadcast frames accepted and forwarded by
the switch. 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.
Broadcast Storm is enabled for all Gigabit 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.
Packet threshold is ignored if Broadcast Storm Control is disabled.
