1.2.15-12 Storm Control
Use the Storm Control Configuration page to set limits on broadcast, multicast and unknown unicast
traffic to control traffic storms which may occur when a network device is malfunctioning, the
network is not properly configured, or application progrAPS are not well designed or properly
configured. Traffic storms caused by any of these problems can severely degrade performance or
bring your network to a complete halt.
You can protect your network from traffic storms by setting a threshold for broadcast, multicast, or
unknown unicast traffic. Any packets exceeding the specified threshold will then be dropped. Note
that the limit specified on this page applies to each port.
Web Interface
To configure the Storm Control settings via the Web Interface:
1. Click Configuration, QoS and Storm Control.
2. Enable storm control for unknown unicast, broadcast, or multicast traffic by marking the
Status box next to the required frame type.
3. Select the control rate for the selected traffic type.
4. Click the Apply button to save your changes or the Reset button to revert to previous
settings.
