Cisco authorized self-study book for CCNP switching foundation learning

Prepare for the CCNP BCMSN exam 642-811 with a Cisco authorized self-study guide. This book teaches you how to:

  • Configure basic parameters for Catalyst switches, including SSH, system host name, and IP address management in both Cisco IOS and Cisco CatOS
  • Employ private VLANs, VTP, and 802.1Q trunking in Cisco multilayer switched networks
  • Deploy 802.1D, 802.1D-2004, 802.1s, and 802.1w STP and utilize advanced spanning-tree features such as UplinkFast and root guard
  • Enable Layer 2 features such as including aggressive-mode UDLD, CDP, and Jumbo Ethernet Frames
  • Deploy Inter-VLAN routing
  • Implement QoS on Catalyst switches at Layers 2 and 3
  • Enable Layer 2 and Layer 3 multicasting features such as IGMP snooping
  • Employ VRRP, HSRP, and Supervisor Engine redundancy for high availability
  • Describe the requirements for IP telephony in multilayer switched networks
  • Implement control plane and data plane security features such as 802.1X and DHCP snooping
  • Deploy Ethernet over long distances with Metro Ethernet solutions such as DWDM and CDWM

CCNP Self-Study: Building Cisco Multilayer Switched Networks (BCMSN), Third Edition, is a Cisco® authorized, self-paced learning tool for CCNP® switching foundation learning. This book provides you with the knowledge needed to build scalable multilayer switched networks, to create and deploy a global intranet, and to implement basic troubleshooting techniques in environments that use Cisco multilayer switches for client hosts and services. By reading this book, you will learn how to improve traffic flow, reliability, redundancy, performance, and security for Layer 2 and Layer 3 switched networks.

This comprehensive book provides detailed information and easy-to-grasp tutorials on design, configuration, operation, and troubleshooting of modern multilayer switched networks. This book introduces Cisco Catalyst® switching architectures, including Cisco Express Fowarding, ternary content addressable memory (TCAM), and the Cisco 6500, 4500, 3750, 3550, and 2950 series of switches. The book places an emphasis on configuring Cisco Catalyst switches with Cisco IOS® Software, with many chapters covering both Cisco IOS and Cisco CatOS. You will also learn about emerging technologies such as multicasting, security, IP telephony, storage area networking, and quality of service (QoS) as additions to the campus network design. The book concludes with a discussion of troubleshooting methodologies and tools. Each chapter opens with a list of objectives to help focus your study. Lab exercises are offered throughout to help illuminate theoretical concepts. Each chapter concludes with a summary of key concepts as well as review questions to reinforce your understanding.

This revision to the popular second edition is fully updated to include designs using new Catalyst products, references to the Catalyst 6500 Sup720, security updates throughout the entire book as well as added coverage of Dynamic Host Configuration Protocol (DHCP) snooping, Address Resolution Protocol (ARP) inspection, ARP throttling, revised metro coverage, and new discussions on voice virtual LANs (VLAN) and Rapid Spanning Tree Protocol (RSTP).

CCNP Self-Study: Building Cisco Multilayer Switched Networks (BCMSN), Third Edition, is part of a recommended learning path from Cisco Systems® that includes simulation and hands-on training from authorized Cisco Learning Partners and self-study products from Cisco Press.
