CLI – The following example displays the LACP configuration settings and
operational state for the remote side of port channel 1.
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
