CISCO 1700c IOS image for GNS3
I am sure you are familiar with the well-known graphical network simulator use for creating networking labs and topologies known as GNS3. There is another network simulator software called packet tracer, the main different of packet tracer over the GNS3 is that GNS3 run with the real Cisco IOS images instead of programing. Some of advantage of using network simulator like is as following:
- If you are student or even you are network professional, it is very difficult for you to buy the costly routers from Cisco. Since GNS3 is a free software so it is a best option for practicing you networking skill, you are required on Cisco IOS.
- You can create and test the network topology before deploying it into real network, you can check for configuration errors. While on live network… never try any new configure until you can crystal clear. J

- Select New Image option and click Browse button. Now select the downloaded IOS image file which you want to use for your lab.
- GNS3 supports both type of files compressed and decompressed and by default IOS files are compressed. If GNS3 asked to decompress the file, select no.
- Click next and continue the Wizard.
- If selected IOS belongs to an outdated device, wizard may display a warning message.In real life, using an outdated device is not recommended. Since GNS3 uses a real Cisco IOS, it also follows the same recommendation and warns us about the outdated IOS. If we are going to use this device only for CCNA exam preparation or to get some hands on experience on Cisco IOS, we can ignore this message.
- Now wizard extracts the hardware information (platform and chassis number) form selected IOS file and lists it in next screen along with an automatically populated device name.If extracted information does not match with device, select the correct platform and chassis number from drop down. If require, you may also adjust the device name.Serial neobook 5.8.4. Verify / adjust the information and Click Next button to continue
- Next screen allows us set the RAM size for this device. By default wizard automatically allocates the minimum recommended memory (RAM) for device. But if require, we can adjust it to match with our specific requirement.
- If selected IOS belongs to a modular device, next screen allows us to install the interfaces in available slots.
- Select appropriate interfaces and click Next button.
- Just like interfaces slots, if selected IOS belongs to a device which has WIC modules, next screen allows to install the WIC interface in WIC slots.
Cisco Ios Images For Gns3
- Select the desire WIC interface and click Next button
- Next screen allows us to put a limit on CPU usage by this IOS. We should always specify this value. This value prevents a faulty or buggy IOS from consuming entire CPU cycles. Once this value is configured, GNS3 does not allow IOS from consuming CPU beyond this limit.
3. Calculating Idle-PC
Click Idle-PC finder button and use the suggested value in this field.
