We did a lot of test about 3 hours with service lost because is heartbeat interface, we tried many many differents configuracions in switch and adapter side (auto,full, etc...) with no results... We use the same cable and switch port with adapter working properly and adapter never shows advertisment 1000.
In this case, we have more servers and only one adapter of one server supports and advertisment one card in 1000/full others, only supports without advertisment.
Support tell us upgrade of all components... but I don't want to make this upgrade because one server is working with the same level of firmwares/drivers and I wan't to know the root problem not only "customer please, upgrade and maybe works"
By the other hand, maybe I will ask for mother board change as these interfaces are integrated.
I will upgrade this "X-file" when I come back of my holidays
Thanks.
