Multicast-Suppression - HP MSR series Command Reference Manual

Default command level
2: System level
Parameters
across: Sets the MDI mode to across. In this mode, pins 1 and 2 are receive pins, and pins 3 and 6 are
transmit pins.
auto: Sets the MDI mode to auto. In this mode, the port negotiates pin roles with its peer.
normal: Sets the MDI mode to normal. In normal mode, pins 1 and 2 are transmit pins, and pins 3 and
6 are receive pins.
Examples
# Set Ethernet 1/1 to operate in across MDI mode.
<Sysname> system-view
[Sysname] interface ethernet 1/1
[Sysname-Ethernet1/1] mdi across

multicast-suppression

Use multicast-suppression to set the multicast suppression threshold on an Ethernet interface, a
subinterface, or a group of Ethernet interfaces.
Use undo multicast-suppression to restore the default multicast suppression threshold.
Syntax
multicast-suppression { ratio | pps max-pps }
undo multicast-suppression
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 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 is 1 to 1488100 pps. Support of MSR routers for
this option varies by router model. For more information, see the usage guidelines for this command.
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 last takes effect.
