For JW OS and WX OS software products, the period of active engineering support will be the current release plus two (2) subsequent releases, or up to eighteen (18) months from the FRS date, whichever occurs first. All software releases are considered major.
Update releases (e.g. service, maintenance, patch) will no longer be created for major software releases after the end of engineering (EOE) date.
JTAC support will continue after EOE for two (2) subsequent releases or up to twelve (12) months, whichever occurs first. After EOE and until EOL JTAC support will be generally limited to investigation and troubleshooting in an attempt to provide solutions and workarounds.
When the release reaches EOL the software images are removed from www.juniper.net and JTAC will only provide support on a commercially reasonable effort basis.
1 No later than the date posted, the date may be earlier if the subsequent releases are reached prior to the months of support option.
2 WX OS 5.3 is only available for the WX-100 Stack.
3 The EOE and EOL dates have been extended for WX OS 5.4, WX OS 5.6, and WX OS 5.7 only and are to be considered an exception to the standard policy noted above.
