Hello dears.
Recently I bought some HPE 1920S switches (PN: JL381A) for my company.
I encountered a problem when I set the switch port to work in the physical mode Full Duplex 100 Mbps. The NIC of my computer continued working in the physical mode Half Duplex 100 Mbps.
At this point I noticed that any network operation was very slow and to solve this problem I configured the switch port to work in the physical mode Auto Negotiate.
The same computer work correctly with HPE 1920 switch (PN: JG924A). On this switch model I have the option auto negociate for duplex mode for all speeds. On the HPE 1920S switch I don’t have this option. I need to change between full or half duplex mode for speeds 10 or 100 Mbps.
My problem occour only HPE 1920S switch. Why my computer can not negotiate correctly the duplex mode with the HPE 1920S switch?
PS: I used a Cat.6 network cable and my device is in software version PD.01.07.
Thank’s for help me.
Best regards,
Leandro Tapia
