The Configure and Verify Switching Concepts module provides you with the instructions and Cisco hardware to develop your hands on skills in understanding, configuring and verifying various features of switches. This module includes the following activities:
- Examine the functionality of the MAC Address Table
- Configure parameters of the MAC Address Table and observe their results
- Examine frame switching methods and understand how they function
- Observe frame flooding and understand its purpose and its vulnerabilities
Exercise 1 - Examining the Functionality of the MAC Address Table
The MAC Address Table, also known as the Content Addressable Memory table, or CAM table, is a data structure that is created and maintained by a switch to keep track of which end-device MAC addresses are associated with which switch port. The purpose of the MAC table is to allow the switch to perform the most fundamental function that distinguishes it from a hub: to create one collision domain per interface.
In this exercise, you will examine how the MAC table functions in order to understand its purpose more fully. Before continuing, make sure the PLABCSCO01 server is also powered on.
Exercise 2 - Examining MAC Address Aging
Dynamically learned MAC addresses remain in the MAC address table for a specific period of time. If there is no activity from the specific MAC address after this specified period of time, the address is removed from the switch. It is possible to adjust this aging time according to your network needs.
Exercise 3 - Frame Switching Methods and Frame Flooding
In this exercise, you will examine the buffers that are used to store frames as they are switched from ingress to egress ports on a switch.
