Default Level
2: System level
Parameters
all: Disables the storm constrain function for all types of packets (that is, unicast packets, multicast
packets, and broadcast packets).
broadcast: Enables/Disables the storm constrain function for broadcast packets.
multicast: Enables/Disables the storm constrain function for multicast packets.
unicast: Enables/Disables the storm constrain function for unicast packets.
pps: Specifies the storm constrain threshold in packets.
max-values: Upper threshold to be set, in pps.
min-values: Lower threshold to be set, in pps, this value ranges from 1 to max-values.
Description
Use the storm-constrain command to enable the storm constrain function for specific type of packets
and set the upper and lower thresholds.
Use the undo storm-constrain command to disable the storm constrain function for specific type of
packets.
By default, the storm constrain function is not enabled.
Do not use the storm-constrain command along with the unicast-suppression command, the
multicast-suppression command, or the broadcast-suppression command. Otherwise, traffics
may be suppressed in an unpredictable way.
An upper threshold cannot be less than the corresponding lower threshold. Besides, do not
configure the two thresholds as the same value.
Examples
# Enable the storm constrain function for unicast packets on GigabitEthernet 1/0/1, setting the upper
and lower threshold to 200 pps and 150 pps.
