While in my pursuit of CCIE R&S, I have been running into a lot of people that ask me if use TCL to test my connectivity. So I took a look at how to use TCL to test with ping. While it does look to test connectivity faster than doing it by hand, I still don't really see the point. If you test each piece as you go, why bother with it? Any thoughts that you have either for or against TCL are appreciated. I don't want to burn brain cycles on something that I don't really need to know how to do.
