Hi,
Customer is asking for the exact purpose of Robust Auto MDIX function. Is the following assumption correct or are there further differences?
- When both link partner support normal Auto MDIX, robust Auto MDIX is not needed regardless whether you have a straight or crossover cable.
- When link partner A does not support Auto MDIX (ie the PHY is forced to either MDI or MDIX), robust Auto MDIX enabled for link partner B ensures to establish the link. If link partner B supports only normal Auto MDIX, there might be cases where you run into a deadlock situation.
Thanks and BR,
KF
