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 resolution is 1 packet per second (pps); i.e., any setting between
500-262143 is acceptable.
Note: Multicast and unknown unicast storm thresholds can also be set
using the CLI (see the “switchport packet-rate” command on
page 25-11).
Command Attributes
• Port 10 – Port number.
• Trunk 11 – Trunk 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: 500-262143 packets per second; Default: 500 pps)
• Trunk 10 – Shows if port is a trunk member.
