Cisco CCNA WAN Protocols-Configuring X.25

Full Description

This unit introduces you to the features and functions of X.25. In addition, you will become familiar with the concept of packet switching as well as with the features of two types of virtual circuits. You will be presented with information that describes the need for Address Resolution and how it relates to transferring data across a network. This unit also introduces the X.25 protocol suite as it is mapped against the OSI reference model. Specifically, the PLP, LAPB, and X.21bis protocols, which make-up the X.25 protocol, are discussed. Also explained is the LAPB frame format and its various fields, as well as the process of encapsulation within X.25 and LAPB protocols. You will learn about the various commands needed to configure X.25, layer 3 parameters such as virtual circuit numbers, packet size, and window size. The unit also covers the steps required to configure the router with these parameters. Finally, you will learn the procedure to configure a router as a local or remote switch and configure X.25 traffic over TCP (XOT).

Outcomes:

Students upon completion of this unit will know, understand and be able to explain The features and functions of X.25, concepts of packet switching, two types of virtual circuits describe the need for Address Resolution, X.25 protocol suite as it is mapped against the OSI reference model, the PLP, LAPB, and X.21bis protocols, LAPB frame format and its various fields, the process of encapsulation within X.25 and LAPB protocols, commands needed to configure X.25, layer 3 parameters, virtual circuit numbers, packet size, and window size, the steps required to configure the router with X.25, and the procedure to configure a router as a local or remote switch and configure X.25 traffic over TCP (XOT).

Assessment:

Students are presented with pre-course test to determine their knowledge before taking the course. During the course students will be presented with a series of quizzes to determine gained knowledge and retention of each section. At the end of the course students will be given a post course test to measure their overall understanding of the subject and retention of knowledge. By comparing their pre and post course test scores, students will be able to measure their knowledge gain.
