z
For a 10-Gigabit port, the value range is 1 to 14881000.
When the threshold is set in kbps:
z
For a Gigabit port, the value range is 1 to 1000000.
z
For a 10-Gigabit port, the value range is 1 to 10000000.
When the threshold is set in percentages, that is, keyword ratio is used, the value range is 1 to 100.
min-values : Lower threshold to be set, in pps, kbps, or percentages.
z
For lower threshold to be set, in pps, this value ranges from 1 to max-values .
z
For lower threshold to be set, in kbps, this value ranges from 1 to max-values .
z
For lower threshold to be set, in percentages, 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.
z
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.
z
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 broadcast packets on
GigabitEthernet
1/0/1, setting the
upper and lower threshold to 2000 kbps and 1500 kbps.
<Sysname> system-view
[Sysname] interface GigabitEthernet 1/0/1
[Sysname-GigabitEthernet1/0/1] storm-constrain broadcast kbps 2000 1500
# Enable the storm constrain function for multicast packets on GigabitEthernet1/0/3 in terms of
percentages of the received multicast packets to the port’s total transmission capacity, setting the
upper and lower threshold to 80% and 15%.
<Sysname> system-view
[Sysname] interface GigabitEthernet 1/0/3
[Sysname-GigabitEthernet1/0/3] storm-constrain multicast ratio 80 15
