Action

To check that a process has restarted, use the following JUNOS CLI operational mode command:

user@host> show system processes extensive

Sample Output 1

What It Means

The sample output shows that the routing protocol process (rpd) was restarted because the process identifier (PID) of the process was renamed from 685, as shown in the Sample Output 1, to 751 as shown in Sample Output 2.
