Traffic Control

The Traffic Control menu contains the following options:
• "Storm Control"
• "Port Security"
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 can be enabled per port 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 for Broadcast packets with a threshold of 200 kbps.
The Storm Control screen provides fields for configuring broadcast storm control.
To configure Storm Control:
1.
Click Security > Traffic Control > Storm Control. The Storm Control screen displays:
