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 Storm Control is enabled by default.
• Broadcast control does not effect IP multicast traffic.
• The specified threshold applies to each individual port on the switch.
Command Attributes
•Port – Port number.
• Type – Indicates the port type. (100BASE-TX, 1000BASE-T, or SFP)
• Protect Status – Shows whether or not broadcast storm control has
been enabled. (Default: Enabled)
• Threshold – Threshold as percentage of port bandwidth. (Options:
64-1000000 packets per second; Default: 64 packets per second)
• Trunk – Shows if a port is a trunk member.
