ExtremeXOS Release Recommendations

The following table lists the recommended ExtremeXOS (EXOS) release and patch for each hardware platform.

Generally speaking, ExtremeXOS software version recommendations are 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.

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.

Note: An asterisk (*) indicates that the hardware is supported on ExtremeXOS version 21.1.1 and later, in addition to the version listed.
