request system application (Junos OS Evolved)

Syntax

Description

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.

Options

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

Restart the application.

Note:

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.

(PTX10001-36MR only) Starting in Junos OS Evolved Release 24.2R1, when the forwarding applications evo-cda-bt and evo-aftmand-bt restart after failure, other forwarding applications also restart (packetio-bt, ppman-aft-bt, evoaft-jvisiond-bt, aft-sysinfo, fabspoked-pfe, and securityd). This behavior makes the system more resilient to abnormal termination of the evo-cda-bt and evo-aftmand-bt applications. When these forwarding applications restart, traffic forwarding stops until all applications are back to normal. Prior to this release, the entire chassis would restart if either evo-cda-bt or evo-aftmand-bt failed. To manually restart the evo-cda-bt, evo-aftmand-bt, or packetio-bt applications if they ever leak memory or file handles, use the request system application application-name node nodename restart operational mode command.
