How to enable jumbo frame support in ESXi.  I currently have a VM up and running, Server 2008, and when I set Jumbo frames to 9000, it reverts back to 1500.  I have intel nicks on the ESXi box, and I;ve seen solutions by enabling jumbo frames to the vswitches using Service console for the licensed ESX server, but since ESXi doesn’ have a service console, is there any workaround?


First  make sure that you’ve got VMWare tools installed on the Guest OS and the Network adaptor is listed as “Enhanced vmxnet” or “Flexible”

- VI Client->Inventory->Guest OS->Right click->Edit settings->Select “Network Adaptor 1″

- On the right will be the Adaptor Type
