I read the following issue with the NIC is these servers. https://listman.redhat.com/pipermail/broadcom-list/2003-January/000006.html But this solution did not seem to help my server, to boot into full duplex mode. I have 20 of them connected to a 2924 with all the ports forced to full duplex 100, so that there can be no confusion. Yet these servers all still come up in 100 half duplex mode. I was hoping someone could shed some light on this issue. Let me know if there is any other information you guys would like to see from me to fix this.
