After looking at the announcement for End of Life support for IOS 12.4 (and you know that IOS 15 is the next version dont you ?) it’s worth looking into the big changes in IOS Feature licensing in case you are not aware of them.
Understating Cisco IOS v15 Licenses. Prior to IOS 15, we used to have 8 IOS images Types (Feature set), by the way it was 12 before it comes 8. Any router was coming with IB Base feature set and according to your company needs you can go for advance feature set and replace the IOS, check the below pic. This book is designed to provide information about late-stage preparation for the Cisco CCNA 200-120 exam. Every effort has been made to make this book as complete and as accurate as possible, but no warranty or fitness is implied. The information is provided on an “as is” basis. The authors, Cisco Press, and Cisco Systems. After IOS Upgrade to c3750e-universalk9-mz.150-2.SE7.bin, The stack was broken. Switch#2 didn’t recognise valid ipbase license with new IOS and came up with lanbase license instead. Therefore stack cannot be composed due to license mismatch between Switch#1 (ipbase) and switch#2(lanbase).

Single Image
IOS 15 is a single software package for the hardware platform that your are using. Now that flash is cheap and large, there doesn’t need to be a different IOS image for the different versions with the advanced features. So you get one software image that has all the features for that platform.
Licensing and Cisco Licensing Manager
You should note that IOS 15 enforces licensing for the Advanced feature sets. That is, you will need to register a license key for every IOS image that needs Advanced IP and receive an activation key to activate those features.
Licensing is basically similar to how the ASA software licenses work today. You need to buy the license, receive the PAK key on a piece of paper, register this on Cisco website to receive an activation key and then enter it into the router. If you want access to the advanced feature sets, you will need to purchase the license and activate it on the router.
Yes, Cisco equipment just got a whole lot harder to manage.
Cisco License Manager
If you are a large company, it is time to implement Cisco Licensing Manager to manage the licenses on all of your equipment. Flir cloud. This will allow you to manage and transfer licenses between physical units.
Operational Procedures
Note that when you replace a faulty router, you will have to activate the license on that router as part of the recovery process. So you will need to update your field engineers to make sure that they know how to do this and perform License Transfer Between Two Working Devices or get on the phone to the TAC or use the web to transfer a license.
I can’t see any point in blogging about this in detail, Cisco IOS 15.0 documentation is clear and concise as always. Cisco really does the best documentation.
You can find out more in the†Software Activation Configuration Guide.

If you face any problem setting it up with GNS3 drop me a message and I will get back to you asap.
GNS3 is an open source (GNU GPL) software that simulates complex networks while being as close as possible from the way real networks perform, all of this without having dedicated network hardware such as routers and switches.
GNS3 provides an intuitive graphical user interface to design and configure virtual networks, it runs on traditional PC hardware and may be used on multiple operating systems, including Windows, Linux, and Mac OS X.

In order to provide complete and accurate simulations, GNS3 actually uses the following emulators to run the very same operating systems as in real networks:
- Dynamips, the well known Cisco IOS emulator.
- VirtualBox, runs desktop and server operating systems as well as Juniper JunOS.
- QEMU, a generic open source machine emulator, it runs Cisco ASA, PIX and IPS.
GNS3 is an excellent alternative or complementary tool to real labs for network engineers, administrators and people studying for certifications such as Cisco CCNA, CCNP andCCIE as well as Juniper JNCIA, JNCIS and JNCIE.
