Manage the Switch via RSLogix 5000 Software Chapter 4
Port The port number includes the port type (Fa for Fast Ethernet and
Gi for Gigabit Ethernet), the base or expansion module number
(1, 2, or 3), and the specific port number. For example:
• Gi1/1 is Gigabit Ethernet port 1 on the base.
• Fa2/1 is Fast Ethernet port 1 on the first expansion module.
The port selected for configuration.
Storm Control Threshold
Settings
N/A Set the threshold values for the broadcast, unicast, and
multicast traffic for each port. The number of packets
being sent is compared against the threshold value. If an
undesirable network event occurs and the threshold
value has been exceeded, a yes value is displayed in the
appropriate column in the Port Status tab and in the
Traffic Exceeded on Any Port parameter in the Switch for
Automation Status tab. Network traffic of the type that
exceeded threshold (broadcast, unicast, or multicast) will
be dropped until it falls below the falling threshold. The
falling threshold is automatically set to 5% less then the
entered threshold value.

Threshold
Units
Check to enable the storm control on the selected port.
The respective threshold value and units are applied to
the selected port when you click Set.
Clear the checkbox to disable the storm control for the
selected port. Zero (0) is applied to the threshold value
and units attributes when you click Set.
Enter the value for the threshold after you choose the
unit of measurement.
If Units is set to pps or bps, enter a value between 0 and
10000000000.
If Units is set to %, enter a value between 0 and 100.
Choose the unit of measurement for the threshold. The
available values for each port are:
• pps (packets per second)
• bps (bits per second)
• %
