3560-X and 3750-X Series support the LAN Base, IP Base, and IP Services feature sets.

The software licenses are not affected by Cisco IOS software upgrades. A software license applies only to a specific feature set. A switch can have more than one software license, but you can enable only one license at a time.

Software Activation is a feature that is preinstalled on the switch, which allows you to install the software license for a feature set.

This Software Activation License is unique to a specific device. In other words, licenses are locked to the switchs unique device identifier(UDI).

A unique device identifier is made up of two components: the product ID (PID) and serial number (SN). Serial number is an 11-digit number that uniquely identifies a device. The product ID identifies the type of device. This information can be found using the show license udi command on the switch CLI. So when you request for a license on the switch, the first thing that you need to have is this UDI of the device.

Permanent licenses are valid for the life of the device on which it is installed. Some examples of permanent licenses are IOS Technology Packages (IPB, UC, SEC, DATA), Feature Licenses such as SSL VPN etc. Temporary License

A temporary software license is limited to a usage period (around 60 days). After the usage period expires, the switch continues to use the temporary software license until it is restarted. Before it restarts, warning messages state the switch is running the feature set without a valid license. After the switch restarts, the switch uses a valid software license based on the hierarchy (ipservices>ipbase>lanbase). If the switch does not have a valid license, it uses the IP base software license.
