ESXi 6.5 with 535T (broadcom) and Jumbo frames issues
We have 3 x DL360 Gen 10 servers. Each with 1x 535T & 1x 562FLR-T. All firmwares are up to date.
Used the HPE Custom Gen9PLus 6.5U2 iso and also esxi patch 10884925
We use 2nd port on each 10Gb adapter to connect to SAN network using Sfotware iSCSI adapter.
Network Configuration is validated with Nimble Storage support and we are finding the the 535T(Broadcom) vmkernel port looses/drops packets. The nic's & SAN and switches have Jumbo frames enabled.
The Intel 562FLR-T works perfectly. and no issues or dropped packes.
All Connected to same switch., Switch had STP disabled on SAN ports and Flow control enable.
Updated the Broadcom driver to the latest from Vmware.com too and still had the issue.
https://my.vmware.com/web/vmware/details?downloadGroup=DT-ESXI65-BROADCOM-BNXTNET-21401900&productId=614
I am guessing driver issue or bug.
Testing using this command where VMk2 is the kernetl port bound only to the 535T port 2 vmnic.
vmkping -I vmk2 -s 8000 -d 192.168.130.240 -c 240
Also
vmkping -I vmk2 -s 1400 -d 192.168.130.240 -c 240 (smaller frame size)

Re: ESXi 6.5 with 535T (broadcom) and Jumbo frames issues
I have created the case and all the logs and information is there. I have had zero contact from HPE escalations on this over the past 2 days since opening and the case on Monday and getting it escalated then. Today is Thursday. Every days I have requested and update.
