Understanding GSS Software Licenses

OL-10410-01
A license package is a predefined set of features bundled together and sold as an
upgrade to the GSS v1.3 software. You can view a GSS software license as a
collection of license packages. For the v2.0 release, GSS capabilities have been
extended through a product coupling with the Cisco Network Registrar (CNR). In
addition, GSS now includes support for Distributed Denial of Service (DDoS)
attack detection and mitigation.
The CNR and DDoS licenses are add-ons; you must separately purchase and
install these two licenses. For a detailed overview and description of the CNR and
DDoS features, see the Cisco Global Site Selector CLI-Based Global Server Load
Balancing Configuration Guide.
To install either the CNR or 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. Do not install the same licence file (files with the
same PAK number) in more than one GSS in the network. If you use the same PAK
number, the GSS with the duplicate license file will be deregistered from the GSS
network. If a clash of duplicate PAK numbers occurs between the primary GSSM
and any other GSS in the network, the other GSS is de-registered even if you
installed a valid PAK number on it prior to installing a PAK number on the
primary GSSM.
To recover a deregistered GSS, perform the following steps:
Uninstall the duplicate license file by using the license uninstall command.
