Techniques you'll need to master:
TCP/IP ( Transmission Control Protocol/Internet Protocol ) addressing is the foundation of almost every modern network today. IP Addresses are used to route data across the Internet and the world. Virtually every PC connected to the Internet is assigned an IP address; even the Palm Pilot I have in my backpack has an IP address. Although you can use a number of other protocols on your Cisco router, most likely it is TCP/IP problems you will face when troubleshooting your Cisco router or switch problems. This chapter begins with an overview of the TCP/IP suite and its applications, and follows with troubleshooting issues regarding those protocols. The LAN protocols covered in the Support Exam include TCP/IP and Novell IPX. The following sections give an overview of the TCP/IP protocol and what you need to know for the exam to troubleshoot this protocol suite.
