Syntax
storm-constrain { broadcast | multicast | unicast } { pps | kbps | ratio } max-values min-values
undo storm-constrain { all | broadcast | multicast | unicast }
Default
Traffic storm control is disabled.
Views
Layer 2 Ethernet interface view
Default command level
2: System level
Parameters
all: Disables storm control for all types of packets: broadcast, multicast, and unknown unicast.
broadcast: Enables or disables broadcast storm control.
multicast: Enables or disables multicast storm control.
unicast: Enables or disables unknown unicast storm control.
pps: Sets storm control thresholds in pps.
kbps: Sets storm control thresholds in kbps.
ratio: Sets storm control thresholds as a percentage of the transmission capacity of the interface.
max-values: Sets the upper threshold, in pps, kbps, or percentage.
min-values: Sets the lower threshold, in pps, kbps, or percentage.
Usage guidelines
To achieve desirable storm protection effect, avoid configuring both the storm-constrain command and
any storm suppression command (unicast-suppression, multicast-suppression, and
broadcast-suppression) on a port.
An upper threshold must be greater than or equal to the corresponding lower threshold. HP recommends
not configuring the same value for the two thresholds.
Examples
# Enable unknown unicast storm control on GigabitEthernet 4/0/1, setting the upper and lower
thresholds to 200 pps and 150 pps.
<Sysname> system-view
[Sysname] interface gigabitethernet 4/0/1
[Sysname-GigabitEthernet4/0/1] storm-constrain unicast pps 200 150
# Enable broadcast storm control on GigabitEthernet 4/0/2, setting the upper and lower thresholds to
2000 kbps and 1500 kbps.
<Sysname> system-view
[Sysname] interface gigabitethernet 4/0/2
[Sysname-GigabitEthernet4/0/2] storm-constrain broadcast kbps 2000 1500
# Enable multicast storm control on GigabitEthernet 4/0/3, setting the upper and lower thresholds to 80%
and 15%.
