Starting the Switch
The exercises in this section focus on knowledge and skills you need before you begin to configure switches.
You should know how to connect to a switch to configure it. You should also be able to interpret the LEDs.
Vocabulary Exercise: Completion
Complete the paragraphs that follow by filling in appropriate words and phrases.
Before configuring a switch, make sure it is plugged in and that the system LED is green. If the system
LED is amber, the switch failed POST and is not operational. To configure a switch, use a rollover cable to
connect the console port on the back of the switch to a COM port on the back of the computer. If using
HyperTerminal as your terminal emulator, you need to configure the port settings in the Properties dialog
box as follows:
Bit per second: 9600
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
However, simply clicking the Restore Defaults button enters these settings automatically.
After the switch boots, you are asked the following question:
Would you like to enter the initial configuration dialog? [yes/no]:
Just as with a router, answering yes begins Setup mode, in which you are asked a series of basic configuration
questions. If you accidentally answer yes or want to abort Setup mode, use the key combination
Ctrl-C. You can also enter setup mode from the privileged user prompt by entering the command setup.
Answering no gives you the Switch> prompt, from which you can use the command-line interface (CLI)
to configure the switch.
You will find that many of the basic configurations of a switch are identical to what you have already
learned for a router. This is because both devices use the Cisco Internetwork Operating System (IOS). For
example, to enter privileged mode, type the enable command. The prompt changes to Switch#. To enter
global configuration mode, enter configure terminal. The prompt changes to Switch(config)#. At any point
in your configuration, you can enter the ? key to get help.
