There is another case in the test of the Network Emulation Tester. If too many MAC addresses are used in the Layer 2 function test, a small number of MACs may not be learned by the chip, so that some traffic will be broadcast and then formed. Packet loss, this time should adjust the number of MAC addresses.
There is also a Lan Network Checker test in which packet loss is caused by uneven HASH of the aggregation port, because in many chips and stacked environments, the cascade port or stack link of the chip uses many high-speed aggregation methods to complete So, if the HASH algorithm does not ensure absolute uniformity, there will be a packet that tells HASH that the traffic rate is too high, resulting in packet loss.
