STORM CONTROL
Use the Traffic > Storm Control page to configure broadcast, multicast, and
unknown unicast storm control thresholds. Traffic storms may occur when
a device on your network is malfunctioning, or if application programs are
not well designed or properly configured. If there is too much traffic on
your network, performance can be severely degraded or everything can
come to 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.
CLI REFERENCES
◆ "switchport packet-rate" on page 1057
COMMAND USAGE
◆ Broadcast Storm Control is enabled by default.
◆ When traffic exceeds the threshold specified for broadcast and
multicast or unknown unicast traffic, packets exceeding the threshold
are dropped until the rate falls back down beneath the threshold.
