The CLI is an interface, based on text. You type in configuration commands and use show commands to get the output from the router or switch.

There are also GUIs (Graphical User Interface) for the routers, switches and firewalls but the majority of the work is done on the CLI. This might sound dated but with so many commands that are available to use, the CLI is much easier to work with than any of the graphical interfaces.

It’s also much easier to copy entire configurations from one device to another. In this lesson, I’ll explain how to access the CLI and the basics of how Cisco IOS works. Access to Cisco IOS CLI Before we can enter any commands, we need access to the CLI. There are three options: • Console • Telnet • SSH The console is a physical port on the switch that allows access to the CLI. We typically use this the first time we configure the switch. Telnet and SSH are both options for remote access. Console Cabling On the switch, you will find one or two physical connectors for the console.

Take a look at the picture below: On the left side of this 2960 Catalyst switch, you see the light blue RJ45 port and a micro-USB port on the left of it. Older switches only have the RJ45 port, newer switches (and other devices) often have both options. Even though it’s an RJ45 port, it’s not an Ethernet port.

We use this connection to connect the switch to a serial port on your computer with the following cable: This cable is called a Cisco console cable and you will need a serial port on your computer. Modern computers or laptops don’t have these serial ports anymore so you might have to use a serial-to-USB cable like this one: This cable emulates a serial port and has a USB connection.

Terminal Emulator There are many terminal emulator applications. If you are new to this, the best one to start with is. It’s free and allows you to connect using a serial connection, telnet and SSH. Once you have downloaded it, you will see the main screen: Make sure you select the “Serial” option.

The default speed is 9600 (baud rate). The COM port will depend on your computer, it might be COM1 but if you are unsure, check the device manager in Windows. Click on Start > Run and enter “devmgmt.msc”: Here is the device manager: Above you can see that on my computer, I have to use COM4.

Change the COM port and click on Open to start the console: Now is a good time to power on your switch or in case it is already powered on, pull the plug so it can reload. First Boot When the switch boots, you will see a lot of stuff on the console. First, it will initialize the flash memory: Boot Sector Filesystem (bs) installed, fsid: 2 Base ethernet MAC Address: 00:11:bb:0b:36:00 Xmodem file system is available. The password-recovery mechanism is disabled. Initializing Flash.

Initializing the flash memory is required since it contains the IOS image (Operating System) of the switch. Its next step is to load the IOS image from the flash memory: Loading 'flash:/c3560-ipservicesk9-mz.122-55.SE10.bin'.@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ File 'flash:/c3560-ipservicesk9-mz.122-55.SE10.bin' uncompressed and installed, entry point: 0x1000000 executing. Download outlook 2011 for mac free. The IOS image is compressed so the switch uncompresses the image and loads it in RAM.
