Understanding GSS Software Licenses
A license package is a predefined set of features bundled together and sold as an upgrade to the GSS version 3.1(x) software. You can view a GSS software license as a collection of license packages.
For the software versions 2.0(x) through 3.0(x), GSS capabilities have been extended through support for an optional license that enables Distributed Denial of Service (DDoS) attack detection and mitigation. The DDoS license is an add-on that you must purchase and install separately. For a detailed overview and description of the DDoS feature, see the Cisco Global Site Selector CLI-Based Global Server Load Balancing Configuration Guide.
To install the DDoS license, your GSS must be running software version 2.0(2) or higher. All previous version features are available and configurable immediately except for the specifically licensed features. If you want to enable the DDoS license package on a particular GSS, you must purchase a DDoS license from Cisco Systems in order to receive a Product Access Key (PAK) number.
Ensure that each GSS in your GSS network possesses a unique license file to avoid any potential problems. A log message is generated when duplicate licenses are detected.
Acquiring, Installing, or Uninstalling a DDoS License File
This section describes how to obtain and then install a DDoS license from Cisco for your GSS devices and how to uninstall a license.
This section contains the following topics:
•Acquiring and Installing a DDoS License File
•Uninstalling a DDoS License File
Acquiring and Installing a DDoS License File
Cisco uses the web-based Software Infrastructure and Fulfillment Technology (SWIFT) application to manage license files as follows:
•Allows you to retrieve or generate a license file for a particular PAK.
•Allows Cisco to track licenses and allows you to recover lost licenses.
•Enables internal support organizations to obtain information about customer licenses.
To obtain a license file, perform the following steps:
1. Connect to the Cisco SWIFT website at the following URLs:
–Use the following website if you are a registered user of Cisco Connection Online:
–Use the following website if you are not a registered user of Cisco Connection Online:
The user interface prompts you for various details about your purchase as part of a software registration process.
2. Enter the required data. After submitting this data, the website authenticates the information, generates a license file, and e-mails it to you.
Note We recommend that you make a back-up copy of your license file after you receive it by e-mail in case the license file is lost or corrupted. Should anything happen to your license file, SWIFT also enables you to regenerate it.
3. Transfer the license file from your PC to the GSS using FTP.
For example, transfer a license file to the GSS as follows:
220 "Global Site Selector FTP"
User (126.96.36.199:(none)): admin
331 Please specify the password.
200 Switching to Binary mode.
200 PORT command successful. Consider using PASV.
ftp: 696 bytes sent in 0.00Seconds 696000.00Kbytes/sec.
4. Install the license once you have transferred your license file by using the license install command in privileged EXEC mode. A valid license file always includes the .lic extension. Otherwise, it is considered invalid and is not installed.
For example, you can install a DDoS license as follows:
gssm1.example.com# license install ddos_new.lic
The license file is copied to the /licenses directory when the installation is complete.
Uninstalling a DDoS License File
To uninstall a license file from the GSS, use the license uninstall command in privileged EXEC mode.
The syntax of this command is as follows:
license uninstall filename
The filename argument is the name of the DDoS license file to remove.
gssm1.example.com# license uninstall ddos_new.lic
