Cisco Documentation (VTPv3, Stackwise, SPAN/RSPAN) Chris Bryant's CCNP All-In-One Videos SWITCHv2 OCG (300-115) I started my CCNP studies before the new exams were announced. I liked the new SWITCHv2, so I used Cisco's 3750 Configuration Guide for IOS 15.0 to study the new topics until the new OCG came out. I finished my studies with the new OCG. Overall, other than a Stackwise which it could've covered a little more, it covered everything I ran into on the exam. I did run into one sim that had me do something [among other SWITCH related configuration] that wasn't on the exam topics or in this book, but the configuration it wanted was something any CCNA should be able to do in their sleep.
