Usage Guidelines Storm control is supported on physical interfaces. 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.
If the port is a user network interface (UNI) or enhanced network interfaces (ENI), you must use the no
shutdown interface configuration command to enable it before using the storm-control command.
UNIs and ENIs are disabled by default. Network node interfaces (NNIs) are enabled by default.
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.
OL-9640-07
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.
Action taken when a storm occurs on a port. The default action is to filter traffic and
to not send an Simple Network Management Protocol (SNMP) trap.
The keywords have these meanings:

•
