Global Knowledge-Cisco - (Page 12) TCN – Troubleshooting Cisco Networks Course 5205 Techniques, tools, tips, and labs for successfully detecting and solving problems in Cisco networks. Course Description This course explores methods for effectively and efficiently troubleshooting problems with Cisco router and Catalyst switch networks. Learn to diagnose and solve problems at the data link, network, transport, and application layers in both Ethernet and WAN networks. You will utilize troubleshooting tools live on the classroom network. Fourteen hands-on labs comprised of Catalyst 2950 Layer 2 switches, Catalyst 3550 Layer 3 switches, and Cisco routers provide real-world scenarios, including resolving network issues received in the form of trouble tickets. This equipment-intensive class is the most comprehensive troubleshooting course available. Hands-On Labs Lab 1: Network Discovery Use Cisco IOS diagnostic commands to discover and document IP addresses, routing protocols, STP configuration, trunk links, EtherChannels, and more. Lab 2: End-System Documentation Use end-system command-line tools and applications to discover and document the configuration of a Windows workstation and a Linux workstation. Lab 3: Tracing Packet Flow on a Router Utilize Cisco IOS tools to examine low-level traffic flow on routers. Examine the ARP protocol. Examine the effects of caching on IOS debug tools. Observe ICMP traffic. Labs 4–6: Physical and Data-Link Trouble Ticket A, B, and C In these three labs, you’ll practice low-level troubleshooting skills on Ethernet, FastEthernet, Frame Relay, and T-1 links. You will be given a preconfigured network with a variety of problems, which you must then diagnose and solve. Labs 7–10: Network Layer Trouble Tickets A, B, C, and D These four labs allow you to practice network-layer troubleshooting skills. You will be given a pre-configured network with a variety of problems, which you must then diagnose and solve. Scenarios will include IP addressing problems, EIGRP, OSPF, and BGP problems, interface problems, redistribution problems, etc. Lab 11: Upper Layer Trouble Ticket A Practice your troubleshooting skills on problems related to transport and application layer protocols, including HTTP, FTP, TFTP, etc. Labs 12–14: Comprehensive Trouble Tickets A, B, and C In these three labs, you’ll practice your troubleshooting skills in complex scenarios that include problems at the physical, data-link, network, and application layers. Special additional problems appear as well to keep you on your toes.
