request system application (Junos OS Evolved)
Syntax
request system application app application-name node node-name restart
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. |
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.
