I am not able to see VSwitch graphical view, please see below pic,i am using VCSA 6.5. please help me on this.
Are you looking for the view that is presented in the vSphere Web Client? The screen you are looking at is on the vSphere Client (HTML 5).
The HTML5 client, which is what you have pictured, does not have the graphical view yet because it is still feature incomplete. This is not a bug, just a gap at the moment.
