Each technology pack contains a set of technology-specific features, and in addition to the basic IPBase technology pack, each advanced technology pack and feature set requires a separate license to be purchased and activated for installation. The most commonly used Technology Pack licenses include IP Base, Data, Unified Communications, and Security. ISRG2IOS supports 2 types of universal images: a universal image with the "auniversal" logo in the image name, which provides all I0S features; and a universal image with the "universalk9_npe" logo in the image name, which provides all I0S features.npe (No Payload Encryption) means that the universal image does not support any strong load encryption and is suitable for countries with encryption restrictions.12.3.2 Router IOS License Application and Installation ProcedureThe new router will be shipped with a pre-installed software image and the corresponding perpetual license for the technology package or feature specified by the customer. If you subsequently apply to purchase a license for the corresponding technology package or feature, there are usually 3 steps as follows.1. Purchase of the technology package or feature to be installed on the routerSoftware-activated licenses require a ProductAuthorizationKey (PAK) for the license and important information about the Cisco EndUserLicenseAgreement (EULA). A PAK is an 11-bit alphanumeric key created by the Cisco manufacturer. It defines the set of features associated with the PAK. The PAK is not associated with a specific device until after the license is created. PAKs can be purchased to generate any specified number of licenses. In most cases, Cisco or Cisco channel partners have activated the licenses ordered at the time of purchase without providing any software activation keys.2. Obtaining LicensesLicenses or license files can be obtained in 2 ways, both of which require the use of a PAK number and a UniqueDevice Identifier (UDI). the UDI is the product ID (PID), serial number (SN), and hardware
