Usage Guidelines Storm control is supported on physical interfaces. When you configure storm control on an interface, it
also affects traffic on Ethernet Flow Points (EFPs) configured on the interface.
You can also configure storm control on an EtherChannel. When storm control is configured on an
EtherChannel, the storm control settings propagate to the EtherChannel physical interfaces.
The storm-control suppression level can be entered as a percentage of total bandwidth of the port, as a
rate in packets per second at which traffic is received, or as a rate in bits per second at which traffic is
received.
When specified as a percentage of total bandwidth, a suppression value of 100 percent means that no
limit is placed on the specified traffic type. A value of level 0 0 means that all broadcast, multicast, or
unicast traffic on that port is blocked. Storm control is enabled only when the rising suppression level is
less than 100 percent. If no other storm-control configuration is specified, the default action is to filter
the traffic causing the storm and to send no SNMP traps.

Specifies the rising and falling suppression levels as a rate in packets per second at
which traffic is received on the port.
pps pps—The rising threshold level for broadcast, multicast, or unicast traffic
•
in packets 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) pps-low,—The falling threshold level in packets 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 pps settings, you can use metric suffixes such as k, m, and g for large number
thresholds.\
Specifies the action to be taken when a storm is detected. The default action is to
filter traffic and to not send an Simple Network Management Protocol (SNMP) trap.
The keywords have these meanings:
shutdown—Error-disables the port during a storm.
•
trap—Sends an SNMP trap when a storm occurs.
