ADC plugin version numbering system
This section explains the version-numbering scheme for ADC Plugin releases running on the ASR 5x00 or Cisco Virtualized Packet Core platform. The version numbering is different for the ADC Plugin release as this release is independent of StarOS software releases.
The fields of the version number as reflected in the ADC Plugin are in the form of INTERFACE.MAJOR.BUILD (e.g., 1.140.514).
· The INTERFACE number indicates the identifier between ASR5x00 and Plugin. This number indicates backward compatibility and only increments when a change will introduce a compatibility issue. This field may increment by ‘1’ when necessary.
· The MAJOR version number indicates a contiguous sequential number that represents incremental changes between releases. This number increments by ‘1’ for each plugin release.
· The BUILD version number indicates the build number that increments with each new build. This is a unique, sequential number across all ADC builds.
This table provides key resources and links to the support information and essential documentation for StarOS and ADC products.
