Enabling Cisco Network Device to Permit Privilege Command

This is series of articles used to describe on how to perform several functions on Cisco-based Network Device. Generally, if those devices such as Router or Switch doesn’t exist or it is very difficult to manage ourselves for getting our own hands on it, Cisco has given an option to be able to just simulate the functions executed in order to configure those devices further.

Cisco has provided an utility which can be used to simulate several commands which can be run similar with the one performed in real devices. The program or app is called Packet Tracer. By using this tool called Packet Tracer, it is quite convenient since it can be installed in local PC. In general, most of the functions available on Cisco’s networking devices can be performed in this simulator.

Packet Tracer itself is explained in Cisco’s official website located in this link, where Cisco Packet Tracer is a powerful network simulation program that allows students to experiment with network behavior and ask “what if” questions. As an integral part of the Networking Academy comprehensive learning experience, Packet Tracer provides simulation, visualization, authoring, assessment, and collaboration capabilities and facilitates the teaching and learning of complex technology concepts.

Basically, it is quite innovative to provide network simulation and visualization tool and helps practicing configuration skills in the desktop or mobile device without having to own the real networking device at all. Below is the step performing how to enable or turn on privilege command mode :

1. Run Packet Tracer. Below is the first look of Packet Tracer itself after successfully executed :

The above is the execution of Packet Tracer in Windows operating system.

2. Just pick any network device just to perform a single command for enabling privilege command mode. In this article, a router is selected. Drag it to the center as shown below :

3. The next step is to select the device placed in the center and double click it to display its detail configuration further. It will then appear a window as shown below :

4. Select tab CLI in the above Router window’s display to start configuring the Router device in a Command Line Interface. The following output will appear :

1. Type ‘no’ in the terminal shown in the above output display to be transferred in Router device command prompt as follows :

1. The following window will then appear :

7. Type ‘Enter’ which is the enter character on the keyboard to display the Router device command prompt as follows :

The above command prompt mode is called the user EXEC mode prompt. So, in order to change it into a privilege command mode just type the following command in the user EXEC mode prompt :

enable

Or, the short version of the command :

ena

The above command will activate the privilege command mode, so the command prompt will be changed as shown in the image below :

The activation of privilege command mode for a Cisco network device which is in this case is a router has already success and finished.
