Statement introduced before Junos OS Release 7.4.
For routing platforms with two Routing Engines, configure a master Routing Engine to switch over gracefully to a backup Routing Engine without interruption to packet forwarding.
The graceful-switchover statement at the [edit chassis redundancy] hierarchy level is not supported for Junos OS Evolved. Graceful switchover is enabled on the Junos OS Evolved system by default.
