Hi,
I have Dell server with Win 2012 and Hyper-V server role installed. I was about to enable jumbo frames in Guest machines(2012 and 2008 R2) but I can only send frame with MTU 2002 bytes max, from wireshark analysis it seems that frames dont pass the hyper-v switch for some reason. The NIC is Broadcom Nextreme with mtu 9000(hyper- v machines have 9014 so I taught that was the issue but the problem occurs also with lower MTU in Guests). I have setup other servers (IBM and Dell with Intel NIC) and they work fine(have MTU 9014). Can anyone encountered this issue? Thanks.
Pete
