Commands
1-27
Parameters
all: Disables the storm constrain function for all types of packets (that is, 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.
pps: Specifies the thresholds to be configured are measured in pps.
max-pps-values: Upper threshold to be set, in pps, representing packets per second.
The value range of max-pps varies with port types.
min-pps-values: Lower threshold to be set, in the range 1 to max-pps-values (in pps).
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.
 Note:
z Do not use the storm-constrain command along with the multicast-suppression
command, or the broadcast-suppression command. Otherwise, traffics may be
suppressed in an unpredictable way.
z An upper threshold cannot be less than the corresponding lower threshold. Besides,
do not configure the two thresholds to the same value.
Examples
# Enable the storm constrain function for broadcast packets on Ethernet 2/0/1, setting
the upper and lower threshold to 200 pps and 150 pps.
