Hello VMWare Community
Since 2 days ago, when I tried to change the MTU of vSwitch0 to MTU 1522 (I have it with a 801.1q trunk to the C2960 Access Switch), I receive the following error:
|Additional Fault Details:|
| VC Build: 1312298|
Error Type: PlatformConfigFault
At first sight , I suspect of a esix driver issue of the vmnic (Broadcom Corporation NetXtreme BCM5722 Gigabit Ethernet), so I search in the compatibility guide for the correct driver (ESXi 5.5 tg3 version 3.131d.v60.4-2vmw N/A VMware Inbox), and I found that the current driver is :
~ # ethtool -i vmnic0
firmware-version: 5722-v3.11, ASFIPMI v6.03
However, as the compatibility guide only says that is VMware Inbox, I cannot download it for my ESXi version (VMware ESXi 5.5.0 build-2068190). I really appreciate any help or advice regarding this issue.
Could well be a driver issue, this NIC wasn't always able to support increased MTU sizes so hopefully the driver update will sort it for you.
You can get the latest driver for your ESXi version through myvmware.com, once logged in go to View & Download Products, click the All Products tab and choose View Download Components for VMware vSphere. Change the version in the drop down at the top to 5.5 then click the Drivers & Tools tab, and expand Driver CDs - the latest driver can be downloaded from here...
Hope this helps

Hello, I just updated de driver and reboot the esxi host, but the issue persists:

from the below KB some of the firmware versions in Broadcom Nics had issues.
