[j-nsp] Interfaces, deactivate vs disable

[Raymond, Steven]

I don't quite understand the difference between deactivate and disable on an interface, from below:

<https://www.juniper.net/techpubs/software/junos/junos60/swconfig60-getting-started/html/cli-configuration-mode43.html>

"In some portions of the configuration hierarchy, you can include a disable statement to disable functionality. One example is disabling an interface by including the disable statement at the [edit interface interface-name] hierarchy level. When you deactivate a statement, that specific object or property is completely ignored and is not applied at all when you issue a commit command. When you disable a functionality, it is activated when you issue a commit command but is treated as though it is down or administratively disabled."

Can anyone please give an example of where it would be better to use either of disable or deactivate, specifically as it pertains to downing an interface?

Thanks
