How to use STM discovery board as external Debugger

[Akshay_]

I have F407G Disc1 board where it has the SWD ports and I want use this board as a standalone external debugger and I went through the manual for the connections but got stuck
Also found a thread in stack exchange where the connections are given as below

 

Where are the pins PA13 and PA14 in SWD here?
It would be really helpful if the name of the respective pins be given here

Get ST-LINKv3, do yourself a favor.

Is port 1 PA13
We have 6 pins here, what does each pin signify here?

An easy test is when you have two similar board, best with different CPUs to see the difference. disconnect the jumper on one board and connect SWD pind 1-4  to the other board ST-Link connector. Keep the orientation. No one board should see the other cpu.
