Enable broadcast storm control on the interface.
Enable multicast storm control on the interface.
Enable unicast storm control on the interface.
Specify the rising and falling suppression levels as a percentage of total bandwidth
of the port.
level—Rising suppression level, up to two decimal places. The range is 0.00 to
•
100.00. Block the flooding of storm packets when the value specified for level
is reached.
level-low—(Optional) Falling suppression level, up to two decimal places. The
•
range is 0.00 to 100.00. This value must be less than or equal to the rising
suppression value. If you do not configure a falling suppression level, it is set to
the rising suppression level.
Specify the rising and falling suppression levels as a rate in bits per second at which
traffic is received on the port.
bps—Rising suppression level, up to 1 decimal place. The range is 0.0 to
•
10000000000.0. Block the flooding of storm packets when the value specified
for bps is reached.
• bps-low—(Optional) Falling suppression level, up to 1 decimal place. The range
is 0.0 to 10000000000.0. This value must be equal to or less than the rising
suppression value.
You can use metric suffixes such as k, m, and g for large number thresholds.
Specify the rising and falling suppression levels as a rate in packets per second at
which traffic is received on the port.
pps—Rising suppression level, up to 1 decimal place. The range is 0.0 to
•
10000000000.0. Block the flooding of storm packets when the value specified
for pps is reached.
pps-low—(Optional) Falling suppression level, up to 1 decimal place. The range
•
is 0.0 to 10000000000.0. This value must be equal to or less than the rising
suppression value.
You can use metric suffixes such as k, m, and g for large number thresholds.
