FIRST INTERATION WITH CISCO IOS

FIRST INTERATION WITH CISCO IOS (Internetwork Operating System)

As it’s the first time you are connected to Cisco router, we are going to start with very basic stuff. (The prompts discussed in this post are shown when you are connected to router’s CLI and have rejected to enter Setup mode. If you are want to know about Cisco Router's Boot Sequence, refer to Cisco router’s startup sequence, post). Let’s go for it then;

            When you connect to a new router via console cable, and the interface and other status messages have been displayed, press the "Enter" key to get started.

You are now connected to your Router at the user mode prompt (Router> prompt). This prompt is broken down into two parts, the hostname-part and the mode-part. "Router" is the Router's hostname and ">" means you are in user mode.

1.         Press RETURN to get started

Router>

2.         Next type the command enable to get to the privileged mode prompt.

Router>enable

Router#

3.         To get back to the user mode, simply type disable. From the user mode, type disable to go back into user-exec mode. You can also type logout or exit to leave the router.

Router# disable

Router>

Router>exit

Router con0 is now available

Press RETURN to get started

4.         You are now again in user-exec mode. Type the command that is used to view all the available commands at this prompt.

Router>?

3. Type the command used to enter Privilege mode.

Router>enable

Router#

4. View the available commands in Privilege mode.

Router#?

5. Type the command that will allow you to see all of the show commands.

Router#show ?

6. Type the command that will allow you to see the active or running configuration.

Router#show running-config

7. At the more prompt, hit the key that will show you the next page of information.

8. Type one of the commands that will log you out of the router.

Router#exit

or

Router#disable
