100% load LAN test failed

[checkbill]

Hi,
I get a fail "Timeout waiting for packet" when setting LAN 100% loading, but I'm delusive why change the setting to 99%, result is passed.

Test Software Enviroment:
OS:Windows 7 Enterprise 32bit EN
LAN Driver:Rel16.2OEMGenPV

Test Hardware Enviroment:
Platform: Intel Sandy Bridge platform
CPU:Intel I7-2610UE
LAN Chip: Intel 82574 LAN

Can you help to reply questions as below? Thank you.
1. Why it happen?
2. If it occur, I can say "LAN function is OK"?

I assume you are using BurnInTest v6.0. In BurnInTest v6.0, a duty cycle of 1 to 99% introduces increasing load in a linear manner. 99% to 100% is not linear because 100% basically sends test packets as fast as the system can. This can be a large difference in load. At 100% some timeouts can occur.

I would try testing with the setting, "Test all available Network Adapters" to "Yes" and specify 1 external "Network Address" IP address (e.g. a router/server on your test network) per network port connected to the test network.

Please note that the duty cycle behavior was changed in BurnInTest v7.0.

I retry with BurnIn v7.0 Pro, it's passed. Thank you.
