Traffic Control

The Traffic Control menu contains the following options:
• "Storm Control"
• "Port Security"
• "Protected Ports"
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.
