	How to Perform Core Dump

Hands-On Lab 1: Network Discovery

Identify the protocols, addresses, and topology of the classroom network.

Hands-On Lab 2: Protocol Analyzers

Learn the interface and operation of Network Associate's protocol analyzers.

Hands-On Lab 3: Multiprotocol Connection

Trace successful logins to identify the steps, devices, and protocols needed when clients utilize TCP/IP, Novell, and connections.

Hands-On Lab 4: Manual Core Dump Perform a manual core dump and confirm that the size of the target file matches that of the router memory.

Hands-On LabS 5-7: TCP/IP Trouble Tickets

Work on three TCP/IP trouble tickets with scenarios including:

Ticket 5- IGRP, RIP, Redistribution problems
Ticket 6- EIGRP and PPP Wan problems
Ticket 7- OSPF, Totally Stubby area problems

Hands-On LabS 8-9: Novell IPX Tickets

Debug two IPX trouble tickets focusing on:

Ticket 8- IPX, GRE Tunneling and RIP version 2 problems
Ticket 9- EIGRP for IPX and Novell SAP filtering problems

Hands-On Lab 10: VLAN Switching Ticket

Troubleshoot and reconfigure a Catalyst 5000 network debugging errors in the following areas:

VLAN trunking protocol
ISL configuration
Spanning tree

Hands-On Lab 11: VLAN to VLAN Routing Ticket

In this "Router on a Stick" trouble ticket none of the VLANs are able to pass data between one another. Identify router and switch errors residing in a multi-vlan network

Hands-On Lab 12: Frame Relay- BGP Ticket

Debug a Frame Relay network consisting of router and FR switch errors.

Ticket 12 is a combination of Frame Relay and BGP. Troubleshoot the frame relay network, and then make BGP work over that network.

Hands-On Lab 13: ISDN-Frame Relay Ticket

In this ticket your group's routers are expected to use ISDN for dialup and dial backup. Test your ISDN configuration knowledge and debug knowledge of the detailed handshaking that takes place when ISDN connects.

Ticket 13 combines ISDN and frame relay. Troubles must be found for both technologies. OSPF is the routing protocol that runs on top of these WAN protocols. Once the WAN is working correctly, you must then find the OSPF bugs.

Virtual Classroom e-Learning Outline

Virtual Classroom e-Learning content follows the Classroom Learning outline above. Hands-on virtual labs are as follows:

Lab 1: Troubleshooting Command Overview

"Troubleshooting Command Overview" covers the usage of low-level hardware and memory-related diagnostic commands. It also covers CDP-related commands.

This lab is an appropriate starting point for students preparing for the Cisco CCNP-track troubleshooting exam.

Lab 2: Using Debugging and Logging Tools

"Using Debugging and Logging Tools" explores the ways in which router debugging messages and system messages can be filtered and logged. Specifically, it covers the use of timestamps, logging buffers, logging levels, and the use of a syslog server.
