This tutorial will help you setup your CCNA, CCNP or CCIE Security Lab with Cisco ASA 8.4 which is currently supported by the latest version of GNS3.
If your network is live, make sure that you understand the potential impact of any command. Refer to the for more information on document conventions. A directory that has the Cisco IOS® Software release name stores the Cisco IOS image as a bin file. The directory stores the image on the system board flash device (flash:). A subdirectory contains the files that you need for web management.
You can use the show version privileged EXEC command in order to see the software version that runs on your switch. The second line of the display shows the version. Note: Although the show version output always shows the software image that runs on the switch, the model name that appears at the end of this display is the factory configuration. This image is either the IP base image, formerly known as the standard multilayer image (SMI), or the IP services image, formerly known as the enhanced multilayer image (EMI). This name does not change if you upgrade the software image. You can also use the dir filesystem: privileged EXEC command.
This command shows the directory names of any other software images that you have stored in flash memory. Before you decide the Cisco IOS Software release to which you want to upgrade the switches, you should:. Read the Release Notes of the particular Cisco IOS Software release.
Make sure the Cisco IOS Software release does have any defects which can affect any of the existing functionality. Refer to the ( customers only) and. Finding the Priority Value of a Catalyst 3750 Switch Priority value determines the Master switch in a stack. The priority value can be 1 to 15. The default priority value is 1. Cisco recommends that you assign the highest priority value to the switch that you prefer to be the stack master.
In this example, the master switch has a priority value of 15. For more information, refer to. 3750# show switch detail Current Switch# Role Mac Address Priority State - 1 Slave 000c.30ae.4f00 9 Ready.2 Master 000d.bd5c.1680 15 Ready The software download center for Catalyst 3750 contains two sets of IOS images for every feature set and versions. One set contains only the IOS image file which has the extension.bin. The other set contains the IOS image plus the web-based device manager which has the extension.tar. This document explains the upgrade procedure with the.tar image as well as with the.bin image.

The.tar file contains the Cisco IOS image file and the files that you need for the embedded device manager. You must use the combined tar file in order to upgrade the switch through the device manager. Cisco IOS Software Release 12.2(25)SEA and earlier referred to the image that provides Layer 2+ features and basic Layer 3 routing as the SMI. These software releases referred to the image that provides full Layer 3 routing and advanced services as the EMI. Cisco IOS Software Release 12.2(25)SEB and later refer to the SMI as the IP base image and the EMI as the IP services image.

Flash File System The 3750 ships from the factory with the installation of a web-based device manager (.tar file) in the flash: directory. The extraction process that takes place with a.tar file creates a Cisco IOS image directory.
The image directory has the same name as the Cisco IOS image (.bin file), but without the file extension. This directory stores the Cisco IOS image (.bin file) along with an HTML subdirectory that contains the device manager files. Issue the dir flash: command in order to view the 3750 Flash file system.
In order to perform CCNA and CCNP hands-on lab exercises, either you need the physical devices or a simulator. Since arranging physical devices, such as Cisco routers and switches is probably not possible for everyone. Fortunately, there are various simulators such as and GNS3 that you can use to perform CCNA/CCNP and other hands-on lab exercises. In this post, you will get the direct links to for Cisco routers, ASA, switches, and even for Juniper routers. One of the great features of GNS3 simulator is that it allows you to perform real-life hands-on lab exercises.
However, you need to download IOS images for GNS3 before you can perform the hands-on lab exercises. GNS3 IOS Images Downloading Links We assume that you have already downloaded and installed the GNS3 simulator on your system. If you have not yet worked with GNS3, we would highly recommend you to visit the following links that will guide you how to download and use GNS3.
Using GNS3 is not as difficult as people think. Note: GNS3 IOS images are subject to copyright of the respective vendors.

GNS3 offers multiple ways to emulate IOS. For older images, we use and maintain Dynamips; an emulator dedicated to emulate some Cisco hardware. Dynamips can run unmodified IOS images. In the new GNS3 1.4, there is a way to run a second category of switches and routers. These are classified as Routing and Switching virtual machines (or R+Svms) for short. What are the differences? Here are the major differences:
Important Points#Availability#
Due to these platforms hitting End of Sale, End of Life, and End of Support status, the images are no longer available for download from Cisco’s support sections. Currently, the c7200 images are the only ones still available for download for those with a support contract.
IOS 15.x#
Only the c7200 series get newer IOS 15 images. All other platforms are now end-of-life and only support IOS 12.4. Please note that the IOSv appliance is based on IOS 15 and there are IOU (IOS on UNIX) images with IOS 15.
Should I use a mainline and technology train image?#
You will find the technology train images to contain the newest features but it may also contain the most bugs. We recommend Mainline over Technology train if you are interested on stability without the need of new features.Please see Cisco IOS Versions and Naming for more information.
Minimum memory#
The minimum RAM is the amount of memory needed for IOS to work at maximum capacity with most feature configured and activated. From experience you can usually use a bit less RAM just fine.
Recommended images#
We really recommend using the c3640, c3660, c3725, c3745 and c7200 IOS images listed below, they have proven to be the most stable in GNS3 provided you use the right amount of RAM and Idle-PC value.
Idle-PC value#
When Dynamips runs an IOS image, a single instance can consume 100% of the processing time for a CPU core or thread. To remedy this, you can supply Dynamips with an Idle-PC value, to consume less CPU. This value will vary between devices/images. To help automate the process of determining a valid Idle-PC value, you can use the Idle-PC finder button when importing a supported IOS image into GNS3:
(Idle-PC values are not required with virtual machines or docker containers. They’re only required for use by the Dynamips emulator)
C1700 Series#
1700s have 1 FastEthernet fixed port (C1700-MB-1ETH) on its motherboard, 2 subslots for WICs (maximum of 2 Ethernet ports or 4 serial ports), and no Network Module slots. Note that interfaces do not use a slot designation (e.g. “f0”)

Cisco Catalyst Switches#
Dynamips is incapable of running IOS images from Catalyst Switches, as it’s unable to emulate the ASICs used in those type of devices.
For switching, you can use an IOU L2 binary image, or an IOSvL2 virtual disk image with Qemu.
Cisco 3750 Ios
However, if you want to use Dynamips you can use the EtherSwitch module with 2600s, 3600s and 3700s Series. Keep in mind that this module works differently (it uses the vlan database etc.) and does NOT support the following features:
To recap: You can import many images using Virtualbox or VMWare. ASIC based models like the Cisco Catalyst switches are impossible to import as a Routing and Switching image.
If you require more switching features, it is recommended to use larger Virtual Machine Switches and Routers (like the ones from VIRL) that run inside your choice of Qemu, Virtualbox or VMWare. For advanced switching IOSv and/or IOU is recommended.
