Support for automatic deactivation and activation of incompatible configurations during unified ISSU (MX960, MX2010, MX2020, MX10003, MX10008, and MX10016)—Starting in Junos OS Release 22.1R1, you can automatically deactivate incompatible configurations on MX Series routers during a unified in-service software upgrade (ISSU). You can then reactivate them after the upgrade is completed or canceled. Currently, this feature is applicable only to clock synchronization configurations for Precision Time Protocol (PTP) and Synchronous Ethernet.
