 This section discusses the software activation for the Cisco Catalyst 3750-E.
 Q. What is software activation, and how does it work?
 A. Software activation authorizes and activates the Cisco IOS Software feature
 set. A special file contained in the switch, called a license file, is examined 
 by Cisco IOS Software when the switch is powered on. Based on the license's
 type, Cisco IOS Software activates the appropriate feature set. License types
 can be changed or upgraded to enable a different feature set. Note that a
 particular license file only functions with the switch for which it was created.
 A license file cannot be copied to a different switch.
 Q. What are the different types of feature set?
 A. There are three types of software licenses: IP Base, IP Services, and
 Advanced IP Services.
 
  IP Base-Enables Layer 2 forwarding and basic Layer 3 routing, including EIGRP
 stub mode.
 
  IP Services-Includes IP Base and enables advanced Layer 3 routing such as OSPF 
 and Multicast routing.
 
  Advanced IP Services-Includes IP Services and enables IPv6 functionality.
 
 Q. What is a product activation key? What are the different types?
 A. Product activation keys (PAKs) are purchasable items, ordered in the same
 manner as other Cisco equipment, that are used to obtain license files for
 feature set on specific classes of switches. (See Table 2.)
 
 Q. Does software activation affect Cisco IOS Software version upgrades?
 A. No, Cisco IOS Software versions can be upgraded without changing the existing
 feature set license.
 Q. With software activation, is there any change to the RMA process?
 A. No, there is no change to the RMA process. However, a switch's product ID
 (PID) and unique device identifier (UDI) identify the software license installed
 at the time of manufacturing. If this license file is changed to a different
 type by the customer, the customer should note the new license type in the RMA
 request. This will help ensure the replacement unit has the appropriate
 installed license type.
 Q. Where is the software license stored on the switch?
 A. The license file is stored on a special area of the flash memory in the
 switch. The license file is not directly viewable within the switch's file
 system, but the command line interface (CLI) exists to view and manage the
 license file.
 Q. What happens if the software license file gets corrupted? Will the switch
 still work?
 A. The license file is stored in a special area of memory that is not directly
 accessible, so it is unlikely to become corrupted. In the event of corruption,
 the switch will continue to function until it is reloaded/rebooted, at which
 time it will only enable the IP Base feature set. If possible, the license must 
 be reinstalled; otherwise the switch can be returned using the
 Cisco RMA process.
 Q. How is a software license changed or upgraded?
 A. A license can be changed or upgraded following a four-step process.
 
 1. Purchase a PAK for the desired type of license.
 
 2. Submit the PAK code and UDI of the switch to the Cisco online license portal.
 
 3. Install the license file returned from the license portal to the switch.
 
 4. Reboot the switch to enable the new feature set.
 The Cisco License Manager can be used to facilitate this process over a large
 number of switches.
