To verify the commands in this book, I had to try them out on a few different devices. The following is a list of the equipment I used in the writing of this book:
• C2620 router running Cisco IOS Software Release 12.3(7)T, with a fixed Fast Ethernet interface, a WIC-2A/S serial interface card, and a NM-1E Ethernet interface
• C2811 ISR bundle with PVDM2, CMME, a WIC-2T, FXS and FXO VICs, running 12.4(3g) IOS
• WS-C3560-24-EMI Catalyst switch, running 12.2(25)SE IOS
• WS-C3550-24-EMI Catalyst switch, running 12.1(9)EA1c IOS
• WS-C2960-24TT-L Catalyst switch, running 12.2(25)SE IOS
• WS-C2950-12 Catalyst switch, running Version C2950-C3.0(5.3)WC(1) Enterprise Edition software
• AIR-WLC4402 Wireless LAN Controller
These devices were not running the latest and greatest versions of Cisco IOS Software. Some of it is quite old.
Those of you familiar with Cisco devices will recognize that a majority of these commands work across the entire range of the Cisco product line. These commands are not limited to the platforms and Cisco IOS versions listed. In fact, in most cases, these devices are adequate for someone to continue his or her studies beyond the CCNP level, too.
This book is for those people preparing for the CCNP BCMSN exam, whether through self-study, on-the-job training and practice, study within the Cisco Academy Program, or study through the use of a Cisco Training Partner. There are also some handy hints and tips along the way to make life a bit easier for you in this endeavor. It is small enough that you will find it easy to carry around with you. Big, heavy textbooks might look impressive on your bookshelf in your office, but can you really carry them all around with you when you are working in some server room or equipment closet somewhere?

Did I Miss Anything?
I am always interested to hear how my students, and now readers of my books, do on both vendor exams and future studies. If you would like to contact me and let me know how this book helped you in your certification goals, please do so. Did I miss anything? Let me know. I can't guarantee I'll answer your e-mail message, but I can guarantee that I will read all of them. My e-mail address is [email protected].
