HP A5830 Series Command Reference Manual page 41

If you execute this command in Ethernet interface view, the configurations take effect only on the interface.
If you execute this command in port group view, the configurations take effect on all ports in the port
group.
When multicast traffic exceeds the threshold you configure, the system discards multicast packets until the
multicast traffic drops below the threshold.
If you set different multicast suppression thresholds in Ethernet interface view or port group view multiple
times, the one configured last takes effect.
Syntax
multicast-suppression { ratio | pps max-pps | kbps max-kbps }
undo multicast-suppression
View
Layer 2 Ethernet interface view, port group view
Default level
2: System level
Parameters
ratio: Sets the multicast suppression threshold as a percentage of the transmission capability of an
Ethernet interface, ranging from 1 to 100. The smaller the percentage, the less multicast traffic is allowed
to pass through.
pps max-pps: Specifies the maximum number of multicast packets that the Ethernet interface can forward
per second:
For GE ports, the max-pps parameter ranges from 1 to 1,488,100 pps.
For 10-GE ports, the max-pps parameter ranges from 1 to 14,881,000 pps.
kbps max-kbps: Specifies the maximum number of kilobits of multicast traffic that the Ethernet interface
can forward per second:
For GE ports, the max-kbps parameter ranges from 1 to 1,000,000 kbps.
For 10-GE ports, the max-kbps parameter ranges from 1 to 10,000,000 kbps.
