Default
Ethernet interfaces do not suppress multicast traffic.
Views
Layer 2 Ethernet interface view, port group view
Default command level
2: System level
Parameters
ratio: Sets the multicast suppression threshold as a percentage of the maximum interface rate. The value
range for this argument is 1 to 100. The smaller the percentage, the less multicast traffic is allowed to be
received.
pps max-pps: Specifies the maximum number of multicast packets that the Ethernet interface can receive
per second. The value range for the max-pps argument varies by device model. For more information,
see About the Command References for HP Unified Wired-WLAN Products.
When the pps keyword is specified and the suppression granularity is larger than 1, the suppression
•
threshold must be no smaller than, and an integer multiple of, the granularity. The multicast
suppression threshold value configured through this keyword on an Ethernet interface might not be
the one that actually takes effect. To display the actual multicast suppression threshold value on an
Ethernet interface, use the display interface command.
When the pps keyword is not specified or the suppression granularity is 1, follow these guidelines:
•
The configured multicast suppression threshold value must be no smaller than 1.
The configured multicast suppression threshold value is the one that actually takes effect on the
Ethernet interface.
Usage guidelines
In Ethernet interface view, the configurations take effect only on the interface. In port group view, the
configurations take effect on all ports in the port group.
When the received multicast traffic exceeds the threshold, the system discards multicast packets until
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 most recently takes effect.
Examples
# Set the multicast threshold to 20% on Ten-GigabitEthernet 1/0/1.

[Sysname] interface ten-gigabitethernet 1/0/1

# Set the multicast threshold to 20% on all ports in the port group named group1.
<Sysname> system-view
[Sysname] port-group manual group1
[Sysname-port-group-manual-group1] group-member ten-gigabitethernet1/0/1
[Sysname-port-group-manual-group1] group-member ten-gigabitethernet1/0/2
