request system software add restart
Syntax
request system software add package-name restart
Description
Perform a unified in-service software upgrade (unified ISSU) to a more recent version of
Junos OS Evolved. A unified ISSU involves minimal disruption of the control plane and data
plane traffic. The software is upgraded by using an application-level restart or warm
restart instead of a reboot, when possible. Use the request system software
validate-restart command before using the request system software add
restart command to determine whether you need an application-level restart or a
reboot.
Note:
You can currently use this command only on QFX5220-32CD switches.
