HI .

 

I am setting up a home lab to build an NSX lab . I am currently running 3 Esxi hosts on VMware Workstation 11 . All the three esxi hosts are running 4 Ethernet adapters each on them .

 

To setup the VXlan setup for my home lab i have modified the .vmx file of the virtual machine and modified the device to vmxnet3 and it works .

 

ethernet1.connectionType = "custom"

ethernet1.virtualDev = "e1000"

ethernet1.wakeOnPcktRcv = "FALSE"

ethernet1.addressType = "generated"

ethernet2.present = "TRUE"

ethernet2.vnet = "VMnet1"

ethernet2.connectionType = "custom"

ethernet2.virtualDev = "vmxnet3"  --------------------- Changed to vmxnet3

 

VMxnet3 adapter type is not supported for VMware workstation and also one of my host has crashed multiple times with the below error message in the log file.

Can someone guide me how to setup an NSX lab on VMware workstation and use 1600 MTU for VXlan traffic. Any help is much appreciated .
