Navigate the Configuration Hierarchy in Juniper Junos (up, top, exit configuration-mode)

After we now know about the Configuration hierarchy, I would like to show you how you can navigate it. What does it mean exactly? Well, think that you are on the user configuration hierarchy level and you want to go back to the top level or maybe to a level in between, would this be possible? The answer is yes indeed it is possible. Let me show you how this can be done.

Let’s do to the system configuration hierarchy level:

root@R1# edit system

[edit system]


I am now on the “edit system” configuration hierarchy level as you can see.

From this level, I can write any command which comes under the “system” command as follows:

[edit system]

root@R1# set ?
