rate. For example, the value range for this argument is 0 to 1488100 on a GE interface and 0 to
59524000 on a 40-GE interface.
kbps max-kbps: Specifies the maximum number of kilobits of multicast 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 multicast storm suppression function to limit the size of multicast traffic on an
interface. When the multicast traffic on the interface exceeds this threshold, the system drops
packets until the traffic drops below this threshold.
Both the storm-constrain and multicast-suppression can suppress multicast storm on a port. The
storm-constrain command uses software to suppress traffic, and it affects the device performance
to a certain extent. The multicast-suppression command uses the chip to physically suppress
multicast traffic, and it has less influence on the device performance than the storm-constrain
command. Do not configure the storm constrain command and the multicast-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 multicast storm suppression threshold to 10000 kbps on GigabitEthernet 1/0/1.
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] multicast-suppression kbps 10000
The actual value is 10048 on port GigabitEthernet1/0/1 currently.
