Restoring the Previous Software Image
If for some reason you need to undo the upgrade, perform the upgrade again except:
• Specify the locations of the upgrade software image and configuration files.
then
• Specify the locations of the original software image and configuration files.
Upgrading ICSR Chassis
The procedure for upgrading primary and backup ICSR chassis is described in Interchassis Session Recovery.
Essentially the procedure requires upgrading the primary and standby chassis using the off-line method while
each is in standby mode.
Performing Dynamic Software Updates
StarOS allows the runtime loading of plugins. All StarOS builds include a "default" baseline plugin.
This feature is currently used to dynamically update the detection logic used to filter P2P applications via the
Application Detection and Control (ADC) feature.
Patching is the process used to install a plugin as an incremental update to a StarOS release. One plugin can
be provided to multiple, compatible, concurrent product releases. A plugin is distributed in the form of a
compressed distribution kit via the internet or by other means (USB stick, CD, etc.).
A plugin is a functional software entity that provides incremental updates to a pre-existing StarOS software
component. Plugins have the characteristic of being dynamically loadable at runtime and do not require a
system restart. A plugin has a name and one or more versions. All plugin names are known to the system at
product release.
For complete information on the Dynamic Software Update process, refer to the ADC Administration Guide.
Managing License Keys
License keys define capacity limits (number of allowed subscriber sessions) and available features on your
system. Adding new license keys allows you to increase capacity and add new features as your subscriber
base grows.
