Storm-Constrain Control - H3C S7500E Series Command Manual

Command Manual – Port Correlation Configuration
H3C S7500E Series Ethernet Switches
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:
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.
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.
