request system application (Junos OS Evolved)



Use this command to stop and then start (restart) an application on the specified node. Use the show system applications command to verify if an application is started or stopped.


app application-name

Specify the application you want started or stopped.

node node-name

Specify the name of the node on which to start or stop the application.


Restart the application.


Make sure to specify the correct node for the application. The sFlow application (sflowd) runs on the Routing Engine node on PTX10001-36MR and PTX10003 routers. It runs on the FPC node on PTX10004 and PTX10008 routers.

Additional Information

(PTX10001-36MR only) Starting in Junos OS Evolved Release 23.2R1, when using this command to restart one of the forwarding applications, such as evo-cda-bt or evo-aftmand-bt, the restart causes traffic forwarding to stop until all applications are back to normal. You might want to restart these forwarding applications if those applications are leaking memory or file handles. When evo-cda-bt or evo-aftmand-bt are restarted, other forwarding applications are restarted as well.
