Parameter
ratio: Maximum ratio of the received unknown unicast traffic to the total bandwidth on
an Ethernet port. The value ranges from 1 to 100 in the step of 1 and defaults to 100.
The smaller the ratio is, the less unknown unicast traffic is allowed.
mbps-value: Maximum bandwidth (in Mbps) for receiving unknown unicast traffic on an
Ethernet port. The range of the mbps-value argument depends on the port type:
z 1 to 100 for 100 Mbps Ethernet ports;
z 1 to 1000 for 1000 Mbps Ethernet ports;
z 1 to 10,000 Mbps for 10 GE ports.
kbps kbps-value: Specifies the maximum bandwidth (in Kbps) for receiving unknown
unicast traffic, in the range of 64 to 1,024,000 in the step of 64.
max-pps: Maximum number of unknown unicast 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 0 to 100 for 148810 Mbps Ethernet ports;
z 0 to 1000 for 1488100 Mbps Ethernet ports;
z 0 to 14881000 Mbps for 10 GE ports.
