Cisco device module gns3v0.7.2 software installation and details

Software Introduction

Cisco device module gns3v0.7.2 all-in-one tool software, excellent Cisco simulation software, and centralized Juniper simulation!
Gns3 is a graphical network simulator that allows you to simulate complex networks.

To make the complete simulation, gns3 is closely related to the following software:
Dynamips, the core program, allows Cisco IOS simulation.
Dynagen. The text-based frontend ends with dynamips.
Qemu, general-purpose and open-source machine simulators and virtual machines.
Gns3 is a good complementary tool. It is truly used by network lab engineers. If the administrator wants to pass ccna certificate, ccnp, CCIP, CCIE, jncia, jncis, and jncie certification.

It can also be used to check configurations for the junos experiment functions of Cisco IOS and Juniper companies. A real router needs to be deployed later. This project is an open-source, free program that can be used in a variety of operating systems, including windows, Linux, and MacOS X.

Function Overview:

High-quality design and complex network topology.
Simulate many Cisco IOS router platforms, such as IPS, PIX and AsA firewils, and junos ..
Simple Ethernet simulation, ATM and Frame Relay switch.
Connect a simulated network to the real world!
Use Wireshark to capture data packets. Gns3 is a graphical network simulator that provides an almost perfect lab environment for Cisco network engineers, administrators, and Cisco certificate candidates.
The gns3 project is an open-source and free program applicable to a variety of operating systems, includingWindows, Linux, and MacOS X.

Installation steps:

1. First install winpcap_4_20.3.exe. This is the underlying package of gns3 and Wireshark packet capture software.

Decompress the gns3 package to the English directory.Note that the directory path cannot contain Chinese characters.. For example, use E:/tool/gns3.

2. Run gns3-0.8.6-all-in-one.exe. All options are available by default.

3. Double-click the gns3 main program and some Prompt Windows will pop out.

Click Close To go to the main interface of the program.

4. Click Edit-preferences-dynamips-test settings to test the Dy environment. The result of normal pass. This step is critical. It determines whether our computer can run gns3.

8. Select the image file and the platform and model (default ). The IOS file name already identifies the models 3640 and 3745. Click Save to close the configuration.

9. Next, calculate the idle value of the vro. This value is used to differentiate the process control between the vrocpu CPU and the host CPU to prevent the simulator from occupying excessive CPU resources. Select the idle value with *. If there are multiple * values, select a value with a large number in the brackets. If not, * is calculated several times. We recommend that you close other running programs when calculating idle.

In this way, drag a vro3640 and click "D" to start the system. The status icon changes from red to green.
