ExtremeXOS Release Recommendations

The following table lists two recommended ExtremeXOS (EXOS) releases for each hardware platform.

The recommendation for Most Stable Release is based on the following criteria:

  • Recommended releases should have no open critical issues introduced in the respective version.
  • Recommended releases should have been deployed in the field for at least three months. As an exception, the latest release would be recommended if critical fixes affecting existing deployment were added to the release.
  • Internal SQA testing must be completed without encountering any new issues.
  • Recommended releases should have been reviewed and accepted by Engineering team leads.

The recommended Latest Feature Release is typically the newest EXOS release. It contains the latest set of features and is fully supported; however, it does not yet have a history of evaluation in the field that is as extensive as the Most Stable Release.

Note: When deploying any software release, customers should always review the Release Notes for known issues that pertain to features and technologies used in their network. Upgrades above these recommendations are suggested only to fix a specific known issue or to implement a required ExtremeXOS feature not included in the currently recommended release.
