Cisco ICND1 1.1: Optimizing and Troubleshooting Switch Security

This course is included in our On-demand training solution.

Overview

After physical access has been secured, there is growing need to ensure that access to the switch via the console port and the vty ports is secure. In addition, it is important to ensure that unused switch ports do not become a security hole. And as devices are added to LANs to accommodate more users, and more networked software applications require more bandwidth, maintaining an acceptable level of network performance becomes an increasing challenge. There are a number of ways to enhance switched Ethernet LANs to meet the demands of users for performance and availability. This course describes how to secure switch ports as well as several performance-enhancement methods. This course also describes methods for identifying and resolving common switched network issues.
