CCNPv6 TSHOOT Chapter 4 Lab 4-1, Layer 2 Connectivity and Spanning Tree Physical Topology All contents are Copyright © 1992–2010 Cisco Systems, Inc. All rights reserved. This document is Cisco Public Information. Page 1 of 24
Logical Topology Objectives Background • Load the device configuration files for each trouble ticket. • Diagnose and resolve Layer 2 connectivity problems. • Diagnose and resolve spanning-tree problems. • Document the troubleshooting progress, configuration changes, and problem resolution. User computers, servers, and printers all connect to the access layer of the hierarchical model. With hundreds or thousands of hosts attached, access devices such as Layer 2 switches are a common source of networking issues. Physical and data-link problems at the access layer can include hardware, cabling, VLAN assignment, spanning tree, trunking protocol, or port security issues. In this lab, you will troubleshoot various Layer 2 problems. For each task or trouble ticket, the scenario and symptoms are described. While troubleshooting, you will discover the cause of the problem, correct it, and then document the process and results. Physical and Logical Topology Diagrams The physical and logical topologies, including interface designations and IP addresses, are provided to assist the troubleshooting effort.
