1-19
z 1 to 10,000 for 10 Gbps Ethernet ports.
kbps kbps-value: Specifies the maximum bandwidth (in Kbps) for receiving multicast
traffic, in the range of 64 to 1,024,000 in the steps of 64.
max-pps: Maximum number of multicast packets allowed to be received per second on
the Ethernet port (in pps). The range of the max-pps argument depends on the port
type.
z 1 to 148,810 for 100 Mbps Ethernet ports;
z 1 to 1,488,100 for Gigabit Ethernet ports;
z 1 to 262,143 for 10 Gbps Ethernet ports.
Description
Use the multicast-suppression command to limit multicast traffic allowed to be
received on the current port.
Use the undo multicast-suppression command to restore the default multicast
suppression setting on the current port.
When incoming multicast traffic on the port exceeds the multicast traffic threshold you
set, the system drops the packets exceeding the threshold to reduce the multicast
traffic ratio to the reasonable range, so as to keep normal network service.
By default, the switch does not suppress multicast traffic.
Caution:
Note that type-A LPUs (including LS81FT48A, LS81FM24A, LS81FS24A, LS81GB8UA,
and LS81GT8UA) do not support multicast suppression.
Examples
# Allow the incoming multicast traffic on Ethernet 2/0/1 to occupy at most 20% of the
bandwidth on the port.
