Configure FTP server in VirtualBox PC to save Start-up configure file.

In this video I already show how to Add virtual-box PC into GNS3. 
As you know, ftp server is a common repository of start up-config file. Use ftp server we can protect our device configuration more safety event broken.
Today, I continue show you how to build FTP server in Virtual-box PC that we added before.


Requirement:
  1. Installed GNs3 and add some ISO images. How to do?. 
  2. You can download ISO image hear 
  3. Embedded Virtual-box PC with GNS3. How to do?
  4. Router R1: f0/0 ip 200.200.200.1 (R2 and R3 are optional)
  5. GNS3-Virtual box PC: e0 ip 200.200.200.4

How to access User Mode in GNS3?

Normally, When we start Router, Switch... in GNS3 it will automatic enter to Privilege Mode. So you also can not execute some commands in User Mode for example Enable, Show...In order to prevent Emulation device automatic enter Privilege Mode you can follow some way as bellow:



1. If you want to apply this configure for device in your project, you'll need to edit file "ios_base_startup-config.txt" in setup folder (C:\program files\GNS3\configs or %USERPROFILE%\GNS3\configs). Open file with Notepad and remove 2 lines have same content as bellow :
 privilege level 15

2. If you only apply this configure for current router your can execute 3 command as bellow:

Console Port:
R1#configure terminal
R1(config)#line console 0
R1(config-line)#no privilege level 15

Aux Port:
R1#configure terminal
R1(config)#line aux 0
R1(config-line)#no privilege level 15

How to add Catalyst Switch in GNS3?

In GNS3 you can not add images for Cisco Catalyst Switch. So all of you will have same with me question.How to make a emulation with Cisco Catalyst Switch?  Don't worry about this inconvenient. This topic i will show you how to overcome it.

2. After finish step 1, you will have some Emulation Router like bellow picture.


To emulate Catalyst Switch in Router image, we must add NM-16ESW module to slot in router.
  • Right-click on router choose Configure

  • In slot drop down list, select module NM-16ESW to add. Click OK to finish module addition.


Note: Router need to be turned off before added port or module.

3. Change symbol Router to Catalyst Switch


In list of symbol, select Ethernet_Switch and apply.


4. Change name of Route name to Switch name.



5. Go to Global Configuration Mode, input command "no ip routing".

Now router became Switch. You can use for your lab.
I hope this guide will help you to study well. Please give me some comment to improve this post more better.

GNS3-Tutorial: Add more port for router

Add more port for router in GNS3:

When you add ISO image in your GNS3 software, each virtual router only have some simple port. Example 1 Ethernet port, 1 Fast Ethernet port..
Some labs request router have at least 2 or 3 or more port. So we must to add some adapter or module into our virtual router.
How to do it? Please view bellow  video! It will help you :)
Please give me your comment to make more useful video. Thanks 

GNS3 - Tutorial: Set IDLE-PC

What exactly is Idle PC value in GNS3?

While simulating your network in GNS3, there is a possibility for 100% CPU usage of your computer. This is due to the Dynamics, the core emulator, doesn't know when the virtual router is idle, or when it’s executing tasks.
Idle PC value calculates the time when the IOS image is idle (not performing any task) and puts the router into an idle state (sleep mode).
Hence it significantly decreases CPU usage on the host without losing the virtual router’s capacity to do real work.
Bellow video will help you set IDLE-PC for virtual router or switch.
