storm-constrain

Syntax
storm-constrain { broadcast | multicast | unicast } { pps | kbps | ratio } max-values min-values
undo storm-constrain { all | broadcast | multicast | unicast }
View
Ethernet interface view
Default 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.
min-values: Sets the lower threshold, ranging from 1 to max-values.
Description
Use storm-constrain to enable broadcast, multicast, or unknown unicast storm control on an Ethernet
port.
Use undo storm-constrain to disable storm control.
By default, traffic storm control is disabled.
To achieve desirable storm protection effect, avoid configuring both the storm-constrain command and
any storm
broadcast-suppression) on a port.
An upper threshold must be greater than or equal to the corresponding lower threshold. HP does not
recommend configuring the same value for the two thresholds.
Examples
# Enable unknown unicast storm control on GigabitEthernet 1/0/1, setting the upper and lower
thresholds to 200 pps and 150 pps.
