Junos OS Release Notes for PTX Series Packet Transport Routers

These release notes accompany Junos OS Release 15.1F5 for the PTX Series. They describe new and changed features, limitations, and known and resolved problems in the hardware and software.

You can also find these release notes on the Juniper Networks Junos OS Documentation webpage, located at http://www.juniper.net/techpubs/software/junos/.

For customers using the Junos OS 15.1F5 release, Juniper Networks recommends that you download the latest Junos OS software release version. If you downloaded the 15.1F5 software prior to March 24, 2016, you can now download the latest version of the 15.1F5 software for the PTX Series. Specific features for the 15.1F5 release are available only in the latest version of the software.

Caution: This release introduces some behavior changes to the unified in-service software upgrade (ISSU) functionality for PTX Series routers. We do not recommend using unified ISSU to upgrade from an earlier Junos OS release to Junos OS Release 15.1.
