Lets assume the initial smalltalk is done now.
You run a Windows 2016 VM on an ESXi 6.5
You are surprised by something related to vmxnet3 adapters and Wireshark reported events.
Shall we use this summary and ask for first bids ?

Can we assume promiscuous mode is enabled for the ESXi and the VM ? -- No

Once i start Wireshark, promiscuous mode is getting enabled. Attached is the screenshot of the output of promiscuous mode.

First output is before running wireshark

Second output is after running wireshark

Third output is after stopping wireshark

You never heard TILT ?
You get that displayed when old Pin ball machines detected excessive force by the user ...
In other words: I got bored by your lack of cooperation.
Fighting for every bit of details is no fun at all ....
We did not even reach the state when first guesses could be useful.
For your information: every word you write here is free of charge - you do not need to pay for each letter or each screenshot ....

You did not even follow the suggestion to enable promiscuous mode on the ESXi which is very likely necessay to run Wireshark.
Hopefully you find somebody else with more patience than me ...

I apologize for not providing much information here and thanks for being patient with me. Actually I am not Sysadmin and i have basic knowledge about ESXi. 

I am taking the help of experts like you here as i am not getting proper help from my sysadmin's. 

Would like to know if there is any impact of enabling promiscuous mode on the ESXi.
