R21xx-HP FlexFabric 11900 Layer 2 LAN Switching Command Reference

34
When you configure the multicast suppression threshold in kbps, the switch automatically uses a multiple
of 64 as the threshold. If you configure a value less than 64, the switch sets the threshold to 64 kbps. If
you configure a value greater than 64, the switch sets the threshold to a multiple of 64 which is greater
than the configured value and is nearest to the value than other multiples.
Examples
# Set the multicast storm 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] multicast-suppression kbps 10000
# Set the multicast 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] multicast-suppression kbps 10000
Info: The actual value is 10048 on this port currently.
