Resolution

When a node is down, interface alerts do not fire because the parent alert already fired an alert. The node is the precedent element and has a built-in dependency that cannot be circumvented. A workaround would require a custom SQL alert as the "interface" type of property to monitor in the alerts would not present variables that would be limited to the exact interface with the issue.

Alternatively, you can also scope the alert so it only monitors interfaces on down nodes.
In the alerts trigger conditions page, go the the scoping section and add this conditional:
"Node Status is equal to Down"
