本文目的：由于思科的IOS平台涵盖了好多功能，有的功能没有开启，就需要license来开启。
安装license的步骤：
s1 获得License文件；
s2 将获得的license文件拷贝到flash；
s3 用命令 license install flash:xxxxxx.lic
s4 reload
从第2---4步很简单。下面主要说如何得到license文件。
PAK码是用钱买的，一般cisco会用纸质的或事email的形式给你，一般没有特别要求，都会是纸质的，看起来比较正式，但是很慢，需要从美国寄过来。
以sup7为例：
4.1 Supervisor Upgrade to Supervisor 7-E or 7L-E
This scenario details the steps needed to install the license during an upgrade to Supervisor 7-E or 7L-E.
Begin the licensing process by browsing to http://www.cisco.com/go/license. There is a PAK (for IP Base [default] or Entservices) which is shipped with each spare Supervisor 7-E and 7L-E. Type in the PAK number, as seen below.
After clicking on the "Submit" button, the system will process the PAK submitted and present the SKU configuration for that PAK, as seen below in the next screen.
Figure 11. PAK showing the License Feature set
One PAK might contain more than one license for a SKU. In the above example, there is only one quantity of the 4500E-LIC-PAK. Once all the information is entered into the screen above, select the "All Done" button in the browser. The next screen asks for the PID and the UDI which was collected before we began the Licensing Process. Enter the PID and the UDI as shown in the screenshot below:
Figure 12. Chassis PID and Serial Number
The next screen asks for the end user's basic information like name, address, company, email address, etc. Feed all the required information as specified in the next screen, and select the "Continue" button. After this the next screen displays information about the PID, Serial Number of the Chassis, Product SKU, PAK number, description, Feature SKU, and other information. Pls see the screen below for example:
Click the "Submit" button if all the above information is accurate.
The system will open a screen stating it is processing the request - and shortly present a screen stating that registration is complete, and a button to download the license, as seen below:
Figure 14. Registration complete
Clicking the "Download License" button in the browser, opens up the next screenshot, where you save the file, which is of the *.lic format, as can be seen in the screenshot below:

Copy the file onto the Switch using TFTP, or RCP or by using the various usual means available. In the example below, the *.lic file is copied from a USB stick onto the bootflash device of the Supervisor.
