H3C S5120-EI Series - Port Auto-Power-Down

33
Parameters
ratio: Sets the multicast suppression threshold as a percentage of the port transmission capability,
ranging from 1 to 100. The smaller the percentage, the less multicast traffic is allowed to pass through.
pps max-pps: Sets the multicast suppression threshold in pps to limit the number of multicast packets
passing through the Ethernet port per second.
• For a Gigabit port, the value range is 1 to 1488100.
• For a 10-Gigabit port, the value range is 1 to 14881000.
kbps max-bps: Sets the multicast suppression threshold in kbps to limit the number of kilobits of broadcast
traffic passing through the Ethernet port per second.
• For a Gigabit port, the value range is 1 to 1000000.
• For a 10-Gigabit port, the value range is 1 to 10000000.
Description
Use the multicast-suppression command to set the multicast suppression threshold on an Ethernet
interface in interface view or a group of Ethernet interfaces in port group view.
Use the undo multicast-suppression command to restore the default.
By default, Ethernet interfaces do not suppress multicast traffic.
If you execute this command in Ethernet interface view, the configurations take effect only on the current
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.
NOTE:
• If you set different multicast suppression thresholds in Ethernet interface view or port-
g
roup view multiple
times, the one configured last takes effect.
• For a particular type of traffic, confi
g
ure either storm suppression or storm control, but not both. If both
of them are configured, you may fail to achieve the expected storm control effect.
