Module 8: Ethernet Switching
Overview
When teaching Module 8, remind students of the evolution of networking devices from repeaters and hubs through bridges and switches. Discuss the real world aspect emphasizing the importance of switching in LANs used today. An upcoming instructional resource on CAC called Packet Tracer will be useful in teaching this module. Consider introducing the concept of VLANs at this point. It is relevant to the discussion of network segmentation in collision and broadcast domains.
 

Module 8 Caution
The concepts of bridging and switching are difficult for students to understand.  Identifying collision domains and broadcast domains requires practice. The theory that segmenting a network creates more collision domains, even smaller ones, confuses some students. Introduction of STP and VLANS in the CCNA curriculum will require additional discussion for students not familiar with the technical vocabulary.

Students completing this module should be able to perform the following tasks:
• Define bridging and switching
• Describe content-addressable memory (CAM) table
• Define latency
• Describe store-and-forward and cut-through switching modes.
• Explain Spanning-Tree Protocol (STP)
• Define collisions, broadcasts, collision domains, and broadcast domains
• Identify the Layer 1, 2, and 3 devices used to create collision domains and broadcast domains
• Discuss data flow and problems with broadcasts
• Explain network segmentation and list the devices used to create segments

Reading to be Done:

READ MODULE 8 ON LINE -- read it twice, even three times to retain the information

There are interactive media options available at the end of some of the pages.  It would be helpful TO YOU if you attempted these.  The quizzes are also a good option.  They give you an idea of what to expect on the test.
