To use the features in the Cisco Devices in cisco classic license, you want to unlock them using the activation method. Since all features available are within the universal image already, you’ll be able unlock the features you wish as you wish them, and in fact pay for these features when you determine that they meet your business requirements. All routers come with one thing known as the IP Base licensing, which is the requirement for installing all different features.
There are 3 completely different technology packages available for purchase that can be installed as additional feature packs on top of the prerequisite IP Base (default), which provides entry-level IOS functionality. These are as follows:
cisco classic license
For example, if you would like MPLS and IPsec, you’ll would like the default IP Base, Data, and Security premium packages unlocked on your router. to get the license, you’ll would like the unique device identifier (UDI), which has 2 components: the PID and therefore the serial number of the router. The show license UDI command provides this data in an output as shown:
Router#sh license udi
you can obtain the cisco classic license file from the Cisco License When you purchase the software package with the features that you want to install, you need to permanently activate the software package using your UDI and the product authorization key (PAK) that you received with your purchase. This is essentially your receipt connect the license with a particular router by combining the PAK and the UDI. If you give us(www.ciscolicense.com) your device information we will deliver a permanent license to you without the need for a Cisco account register.
You now need to activate the license on the router. you need to make the new license file available to the router either via a USB port on the router or through a TFTP server. Once it’s available to the router, you’ll use the license install command from privileged mode. Assuming that you copied the file into flash memory, the command would look like something like this:
Router#license install flash:FTX1628838P_201302111432454180.lic
You need to reboot to have the new license take effect. Now that you
have your license installed and running, how do you use Right-To-Use
licensing to check out new features on your router?
The show license feature command provides the same information as show license, but it’s summarized into one line as shown in the next output:
Router#sh license feature
Note: By introducing Cisco Smart Licensing, the classic licenses are not supported on recent devices any more.
