The size and complexity of modern networks almost ensures that problems will sometimes occur in the delivery of IP packets. The Internet Protocol provides a mechanism for reporting error information when those problems arise. In this course, you'll learn how The Internet Control Messaging Protocol, or ICMP, provides error reports and diagnostic messages. You will learn the layout of ICMP messages and the common ICMP message types and their functions. In addition, you'll be able to recognize several common types of ICMP messages by examining output from a protocol analyzer. Finally, you'll be able to explain how the ICMP time exceeded message is used with trace route.
