Enabling Jumbo Frames on VMware and Windows

Once you have enabled jumbo frames on the physical switch we should proceed by enabling them within vSphere and the VM.

To turn on jumbo frames for a specific vSwitch within vSphere: From within the vSphere Web Client go to: Manage >> Networking >> Virtual Switches >> Edit settings of desired vSwitch >> Properties >> Change the MTU parameter. This configuration will then apply to all physical NICs connected to the vSwitch.

To turn on jumbo frames for a specific VM running Server 2012:
From within Device Manager identify the virutal NIC - Right-hand click >> Properties >> Advanced >> Jumbo Packet.
