Alameda CA he CCNA courseware for the new CCNA exam covers the Cisco Catalyst 1900 switch. You need to have a good understanding of how this switch works. The 1900 switch is a low-end model in the Cisco Catalyst switch family. You can buy two different models in the Catalyst 1900 switch family the 1912 and the 1924. The 1912 switches have 12 10BaseT ports and the 1924 switches have 24 10BaseT ports. Each has two 100Mbps uplinks either twisted-pair or fiber. Since the 1900 switch can now run a version of the Cisco IOS you can use it to thoroughly understand switching through all Cisco switching products. Not all Cisco switches run a version of the IOS but they will eventually. In this appendix you will learn how to start up and configure a Cisco Catalyst 1900 switch using the Command-Line Interface CLI . I will begin by explaining how to connect a console cable and then I will discuss what happens when a 1900 switch is powered up. After you learn how to connect a console cable to the switch and get the switch working I will teach you the basic configuration commands that you can use on the 1900 switch. After you learn the basic commands I will show you how to configure Virtual LANs VLANs on the switch as well as ISL routing and Virtual Trunk Protocol VTP . The basic commands covered in this appendix include the following Setting the passwords Setting the hostname Configuring the IP address and subnet mask Identifying the interfaces Setting a description on the interfaces Copyright 2000 SYBEX Inc. Alameda CA Features of the 1900 Switch 569 Defining the port duplex of a port Verifying the configuration Managing the MAC address .
