storm-control
storm-control
To enable broadcast, multicast, or unicast storm control and to set threshold levels on an interface, use
the
storm-control command in interface configuration mode. To return to the default setting, use the no
form of this command.
storm-control {{ broadcast | multicast | unicast } level { rising_level [ falling_level ]} | bps bps
[ bps-low ] | pps pps [ pps-low ]}} | { action { shutdown | trap }}
no storm-control {{ broadcast | multicast | unicast } level } | { action { shutdown | trap }}
Syntax Description broadcast Enables broadcast storm control on the interface.
multicast Enables multicast storm control on the interface.
unicast Enables unicast storm control on the interface.
level
rising_level
[ falling_level ]
Specifies the rising and falling suppression levels as a percentage of total bandwidth
of the port.
• rising_level —The rising threshold level for broadcast, multicast, or unicast
traffic as a percentage (up to two decimal places) of the bandwidth. The port
blocks traffic when the rising threshold is reached. The range is 0.00 to 100.00.
•
(Optional) falling_level—T he falling threshold level as a percentage (up to two
decimal places) of the bandwidth. This value must be less than or equal to the
rising suppression value. The port forwards traffic when traffic drops below this
level. If you do not configure a falling suppression level, it is set to the rising
suppression level. The range is 0.00 to 100.00.
If you set the threshold to the maximum value (100 percent), no limit is placed on
the traffic. If you set the threshold to 0.0, all broadcast, multicast, and unicast traffic
on that port is blocked.
level bps bps
[ bps-low ]
Specifies the rising and falling suppression levels as a rate in bits per second at which
traffic is received on the port.
•
bps bps —The rising threshold level for broadcast, multicast, or unicast traffic
in bits per second (up to one decimal place). The port blocks traffic when the
rising threshold is reached. The range is 0.0 to 10000000000.0.
•
(Optional) bps-low —The falling threshold level in bits per second (up to one
decimal place). It can be less than or equal to the rising threshold level. The port
forwards traffic when traffic drops below this level. The range is 0.0 to
10000000000.0.
For bps settings, you can use metric suffixes such as k, m, and g for large number
thresholds.
