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 for Gigabit ports is 1 packet per second (pps); i.e., any
setting between 500-262143 is acceptable. However, the resolution for
the 10 Gigabit port is in steps of 1041 pps.
Command Attributes
• Port
9
– Port number.
• Trunk
10
– Trunk number
• Type – Indicates the port type. (1000BASE-T, SFP, or 10GBASE-LR)
• Protect Status – Shows whether or not broadcast storm control has
been enabled. (Default: Enabled)
• Threshold – Threshold as percentage of port bandwidth.
(1000BASE Options: 500-262143 packets per second; Default: 500 pps,
10GBASE Options: 1041-262143 packets per second; Default: 1041 pps)
• Trunk – Shows if port is a trunk member.
