ICND2 2.0: VLANs and Spanning-Tree

Anyone wishing to obtain Cisco Certified Network Associate (CCNA) 200-120 certification that validates the knowledge and skills required to install, operate, and troubleshoot a medium-sized network, including connecting to a WAN and implementing network security. Interconnecting Cisco Network Devices Part 2 (200-101 ICND2) is an essential course for students preparing for the CCNA Routing and Switching certification or the ICND2 certification. Students pursuing the CCNA Routing and Switching certification should attend parts 1 & 2 of the ICND course.Network administrators, network engineers, network managers, network designers, and project managers. Familiarity with network fundamentals, implementing local area networks, Internet connectivity, managing network device security, implementing WAN connectivity and basic IPv6 connectivity is recommended.

Description
This course starts with a review of VLAN and trunk technology. Understanding how VLANs and trunks operate and which protocols are associated with them is important for configuring, verifying, and troubleshooting VLANs and trunks on Cisco access switches. This course also addresses some of the common reasons that port connectivity, VLAN configuration, and trunk establishment can fail. It describes what information to look for to identify the source of the problem and determine how to solve it.
Switched networks introduce redundancy, so an STP loop-avoidance mechanism is needed to prevent undesirable loops. Most complex networks include redundant devices to avoid single points of failure. Although a redundant topology eliminates some issues, it can introduce other problems. STP is a Layer 2 link management protocol that provides path redundancy while preventing undesirable loops in a switched network. This course closes with a review of the problems that are caused by redundant switched-network topologies and the functions of STP that prevent these problems.
