advanced switching techniques and practices. Written in smaller,
easier to absorb chapters, this book breaks down large concepts
into manageable learning blocks, making it even easier to
comprehend and retain the large amount of learning required for
this exam. As part of the CCNP/CCDP certifications, switching is an
important building block that all networking professionals must
master. Cisco Press teaches and prepares candidates for this
challenging professional-level exam with all the features from the
Exam Certification Guide Series that they have come to expect. Pre-

learning materials, real-world case studies, and, of course, the
200-plus question electronic testing engine on the CD-ROM included
in the back of the book. New coverage includes reviews of new
switching hardware and advanced topics. An emphasis on IOS Software
commands in the Catalyst 3550, 4000, and 6000 families is included,
as well as Cisco Express Forwarding (CEF), transparent LAN
services, QoS Classification, and IP telephony configuration.
