CCNA 2.5.c: How to configure Dynamic Trunking Protocol (DTP)

How to configure Dynamic Trunking Protocol (DTP). It's good to know, especially if you're wondering how switchports automatically negotiate before you even configure them. I recommend understanding how it works and then turning it off completely with the "switchport nonegotiate" command. Turning it off helps you maintain more control over your switches and what's connecting to them.
