NOTE: All Redline releases prior to Redline 3.2 have reached End of Engineering and End of Life Dates.

For DXOS 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 Redline 4.2 was re-branded to DXOS 5.0 in October 2005.

3 DXOS 5.3 is the final release of DXOS software and will be supported until the End of Support (EOS) date for all DX platforms is reached in July of 2013.
