Article ID: KB19675 KB Last Updated: 27 Mar 2013Version: 2.0
This article provides information about the meaning of the Starting child '/sbin/ifinfo' and Cleanup child '/sbin/ifinfo' messages.
Often, customers are able to view the following messages, when they are operating the router:

mgd[19228]: %INTERACT-6-UI_CHILD_STATUS: Cleanup child '/sbin/ifinfo', PID 19236, status 0

ifinfo is a short-live process that is created, when the show interfaces command is issued via the Junos CLI. Some of the Junos CLI commands are associated with the shell command and in this case, the ifinfo command is executed. If you type the ifinfo command in the shell mode, the output will be in the XML format:
lab@rollpanna-re0> start shell user root
root@rollpanna-re0% ifinfo ge-0/0/0
<interface-information xmlns="" junos:style="normal">
<admin-status junos:format="Enabled">up</admin-status>
