I've been looking at the default configs that the switches at my company have and I was wondering what these lines do. I asked my trainer, but he said HE didn't know because the guy who taught him just told him "that's how we do it".
If you know what they do, a line-by-line explanation would be preferable because I'm still not super knowledgeable of all this.

aaa authentication login default local
aaa authorization exec default local
