Summary

As your network grows and multiple users move around and add devices to or remove devices from the jacks in the wall, port security allows you to manage the devices that come and go on your network. Switches allow you to control access using the MAC address of each device as an identifier and stop intruders at Layer 2. The information covered on Day 23 and today should give you the tools to better manage and secure a switched network. You can further review the topics from today on pages 129–172 of CCNA Flash Cards and Exam Practice Pack (CCENT Exam 640-822 and CCNA Exams 640-816 and 640-802), Third Edition.
