Configuring the Switch

Setting Broadcast Storm Thresholds
Broadcast 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 broadcast traffic on your network, performance can be severely degraded or
everything can come to complete halt.
You can protect your network from broadcast storms by setting a threshold for
broadcast traffic for each port. Any broadcast packets exceeding the specified
threshold will then be dropped.
Command Usage
• Broadcast control does not effect IP multicast traffic.
• The specified threshold applies to each individual port on the switch.
Note:
Multicast and unknown unicast storm thresholds can also be set using the CLI
(see the “switchport packet-rate” command on page 24-7).
Command Attributes
