When I wanted to add IOU L2 Switch image on GNS3, I got the following license error. Desene animate dublat in romana torrent org full.

When I checked the license, I realized there was no license key.

I explained the solution :

1- Access the shell of your VM

2. Download the Keygen using the following command.

4. After running this command, a file called iourc.txt will be created.

5. Copy and paste the license key in the file to the Preference> IOS on UNIX section of GNS3.

6. Finally, everything is green😀!!!

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.

Dec 12, 2013 Solved: Hi all, I have a simple question: I would like to install a new IOS on a 3750 switch, installed IOS version is 12.x, the actual version is 15.x. I'm able to download the 15.x IOS software with my cisco account, but I am entitled to install. Hi Everyone, I think this is a fairly easy question, but I can't find a direct answer anywhere. We have a bunch 2960-S switches running the IOS 12, can I freely upgrade them to the IOS 15? I need to stack the devices with X switches which are running the IOS 15 version. All 2960-S switches have lan.

Prior to IOS 15 , we used to have 8 IOS images, all routers came with IPBase image and according to your needs you can choose what IOS image to install on your router as each image had different features than others as illustrated below.

The universal IOS image is loaded by Cisco manufacturing on all shipped routers. An IOS universal image contains all IOS features. Feature sets in the universal image are unlocked using licensing keys, i.e. the level of IOS functionality available is determined by the license applied to the device. A new license only needs to be applied to upgrade IOS functionality on the router. Maintenance upgrades of IOS, i.e. moving from one IOS universal image version to another, does not require a new licensing key. Reboot of a router is also licensing transparent.

Each device ships with universal image, IPBase, DATA, Unified Communications (UC) and Security (SEC) technology packages are enabled in the universal image via Cisco Software Activation licensing keys.

The details of each technology package license can be found in the table below. The new ISR routers also offer a Software Activation feature license and right to use feature licenses. The Software Activation feature licenses use the same Software Activation model as the technology package licenses, while right to use feature licenses are not enforced. Feature licenses work in conjunction with technology package licenses, e.g. the SSLVPN feature license requires a SEC technology package license.

How to get License from Cisco and how to install it in my Router ?

Purchase the software package or feature that you want to install. You receive a PAK with your purchase.

  • The Product authorization key PAK is provided to you when you order or purchase the right to use a feature set for a particular platform. The PAK serves as a receipt and is used as part of the process to obtain a license

Get the license file using one of these options:

  1. Cisco License Manager, which is a free software application available at http://www.cisco.com/go/clm.
  2. cisco license registration portal http://www.cisco.com/go/license

What you will do is Convert the PAK to a license by entering the PAK and the unique device identifier (UDI) into the CLM or Cisco Product License Registration portal

  • The UDI is a combination of the product id (PID), the serial number, and the hardware version.
  • The UDI is printed on a label that is located on the back of every device and also can be known through (CLI) and SNMP

To know what is your UDI , type show license udi as follow

After entering the appropriate information, you will receive an e-mail containing the license information that you can use to install the license

  • Copy the license file received from the Cisco Product License Registration portal to the appropriate file system on the device.
  • Click the Install button on the web page.

A Software Activation License is an XML text file with a .lic extension and even can be opened by any text editor.
