Lesson 3: Windows Troubleshooting (2.0) hours

Windows Troubleshooting teaches you how to troubleshoot connectivity issues in the network using the commands ping, pathping, and tracert, and using the appropriate syntaxes with each of these commands, use the ipconfig and winipcfg commands to add, remove, and troubleshoot Dynamic Host Configuration Protocol (DHCP) information on a hosts interface, understand the nslookup command and its modes and syntaxes in order to troubleshoot and resolve DNS query problems, understand the route command, its syntaxes, and its subcommands in order to use them to statically add, change, and remove known routes through the network on the local host, and use nbtstat and netstat command syntaxes in order to troubleshoot many problems in your network and on the local host. This course provides an introduction to Windows troubleshooting techniques. Command syntax and how its used in troubleshooting Windows issues is presented for the most commonly used commands such as ipconfig, ping, tracert, nslookup, netsta,ftp, and telnet. In addition, troubleshooting common problems from Windows clients is discussed. Topics include The ipconfig Command, The winipconfig Command, The ping Command, The tracert and pathping Commands, The nslookup Command, The netstat Command, The route Command, The arp Command, The ftp Command, and The telnet Command.

Lesson 4: The Physical and Data Link Layers (2.0) hours

The Physical and Data Link Layers teaches you how to describe the show commands that can be used to view the configuration and to monitor and view the statistics of Cisco interfaces, articulate the need for Network Monitoring Systems, understand what SNMP is and how it works with Network Monitoring Systems, troubleshoot switched connections, switch hardware and software, VTP, ISL, and Spanning Tree Protocol configurations, identify switch troubleshooting and configuration software, learn which diagnostic tools to apply to VLAN configuration problems, and troubleshoot inter-VLAN routing configurations, trunk links, switches, and routers. This course explains how to utilize tools and commands that can help identify problems with a Cisco router or switch, network cabling, or other network problems affecting the Physical layer of the network. These basics include using the show commands, physical tools (such as cable testers), management system software, and protocol analyzers (sniffers). The Set/Clear command set IOS, such as that used on the Cisco 5000 series switch, and the Cisco Command Line Interface (CLI) IOS, used in the Cisco 4500 series switch, are discussed. Topics include Equipment for Troubleshooting, Troubleshooting with the show Command, The Cisco Discovery Protocol (CDP), Configuration and Fault Management, Hardware Troubleshooting, Layer 2 Troubleshooting Basics, Catalyst Switch Troubleshooting Software, Remote Monitoring (RMON), Lost Password, and Switch Troubleshooting Commands.

Lesson 5: Virtual LANs (2.0) hours

Virtual LANs teaches you how to differentiate between trunk links and access links, use VTP and VTP pruning, differentiate between dynamic and static VLAN ports, differentiate between internal and external route processing, configure VLANs, trunking, VTP, and VTP pruning on a Catalyst switches, troubleshoot switched connections, and troubleshoot inter-VLAN routing configurations. This course focuses on Virtual LANs (VLANs), which were created by the different switch manufacturers to provide individual broadcast domains. By assigning each port to an individual VLAN, each VLAN becomes its own broadcast domain. Additional topics presented include VLAN trunks, pruning, route processing, and troubleshooting switched connections and routing configuration Topics include VLAN Trunks, The VLAN Trunk Protocol, VLAN Advertisements, Inter-VLAN Routing, VLAN Configuration, VLAN Trunk Configuration, VLAN Pruning, Assigning a VLAN Membership to a 1900 Series Switch, Static and Dynamic VLANs, Configuring and Enabling VTP, Configuring Inter-VLAN Routing, Inter-Switch Link, and The IEEE 802.1Q Standard.

Lesson 6: Serial Links (2.0) hours

Serial Links teaches you how to troubleshoot Frame Relay and X.25 problems, troubleshoot serial link problems, determine whether serial link problems are hardware or software issues, perform a local or remote loopback test, troubleshoot IOS serial link configuration issues, and use IOS commands that will aid in isolating problems. This course details how to troubleshoot serial links and the protocols used on serial links. Techniques for troubleshooting serial links, including CSU/DSU Loopback Testing and common serial link troubleshooting commands, are presented. In addition, the course discusses Frame Relay troubleshooting and techniques for troubleshooting X.25. Topics include Serial Link Symptoms, Troubleshooting Techniques for Serial Link Problems, CSU/DSU Loopback Testing, Serial Link Troubleshooting Commands, Troubleshooting Frame Relay, Frame Relay Troubleshooting Commands, Troubleshooting X.25, and X.25 Troubleshooting Commands.

Lesson 7: Routing Protocols (2.0) hours
