Arista Networks' Access Point (AP) Software Release Policy and Life Cycle guidelines help customers and partners facilitate Access Point upgrades and plan multi-year infrastructure deployment. Arista will support each major AP software release for 18 months from the date of posting of the last feature release for a particular train.
To assist customers in selecting the right AP software release for their environments, Arista follows a standard naming convention for AP software releases. The naming convention identifies if a particular release is integrating new feature functionality, or has reached software maintenance mode.
Each AP software release is identified with either the letter "F" indicating that the release contains new Functionality or "M", denoting that the release is in the Maintenance phase. An M release only receives incremental fixes and no new functionality is added.
New Feature Phase
- AP software releases will be identified with the letter "F" indicating that the release contains new features/functionality.
- TAC support available
Maintenance Phase
- AP software release will be identified with the letter "M" for maintenance phase An “M” release only receives incremental fixes and no new functionality is added
- TAC support available
The following diagram depicts the release phases using an example.
The following table depicts the Arista AP release support matrix, including the timelines for each major Arista AP software train (based on the 18 month lifecycle policy) and includes current state of TAC support for each train. As a special case, when an AP platform or a series of platforms (say, 2xx APs) end-of-life (EoL) is announced, the last supported release version (say, 21.2.F) of that platform or series of platforms enjoys maintenance support (existing feature support, vulnerability fixes) for the period of its life from the date of EoL announcement.
