Importance of debug and where to
Maybe this is my bad, but all the way through my CCNA, CCNP, and even CCIE R&S Written studies I haven't used the debug commands often or at all. I felt most of the time I could get away with finding the information I needed to know with doing the different "show" commands.
Personally, what I think turned me off to debug is all the information that it puts out, and the stress of typing "u all" when my screen is being overrun.
There is also the problem of debugging locking you out of the console.
So now that I am studying for the CCIE R&S Lab:
1) How important is it to really know and use debug? Is it absolutely essential for troubleshooting section?
2) Where do you think you can get away with just the "show" commands, and where is debug required? (i.e. ... in trunking and STP "show" commands are enough, but in PPP you really need to use debug).
Thanks for your thoughts!
PS: I really did not see a high level discussion on this topic when I searched the forums ... if there is one, and I missed it, thank you for the link if you have it.
