R211x-HP Flexfabric 11900 Layer 2 - LAN Switching Command Reference
37
kbps max-kbps: Specifies the maximum number of kilobits of broadcast traffic that the Ethernet interface
can forward per second. The value range for this argument (in kbps) is 0 to the maximum interface rate.
Usage guidelines
You can use the broadcast storm suppression function to limit the size of broadcast traffic on an interface.
When the broadcast traffic on the interface exceeds this threshold, the system drops packets until the
traffic drops below this threshold.
Both storm-constrain and broadcast-suppression can suppress broadcast storm on a port. The
storm-constrain command uses software to suppress broadcast traffic, and it affects the device
performance to a certain extent. The broadcast-suppression command uses the chip to physically
suppress broadcast traffic, and it has less influence on the device performance than the storm-constrain
command. Do not configure the storm constrain command and the broadcast-suppression command at
the same time. Otherwise, the traffic suppression result is not determined.
When you configure the suppression threshold in kbps, the actual suppression threshold might be
different from the configured one as follows:
• If the configured value is smaller than 64, the value of 64 takes effect.
• If the configured value is greater than 64 but not an integer multiple of 64, the integer multiple of
64 that is greater than and closest to the configured value takes effect.
To determine the suppression threshold that takes effect, see the prompts on the device.
Examples
# Set the broadcast suppression threshold to 10000 kbps on Ten-GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] broadcast-suppression kbps 10000
The actual value is 10048 on port Ten-GigabitEthernet1/0/1 currently.
