Here is the situation....
I created a map with ONLY the serial interface of each of our routers. I have over 1000 routers I need on this map and don't want to poll every single interface the router has on it, otherwise I will end up with 20,000 interfaces.
When all the interfaces are UP, the map shows GREEN. This is working as expected.
When a serial interface goes DOWN, the map shows GREY (not RED).
How do I get the status to go RED and into a DOWN state rather than UNKNOWN? Do I really have to put the actual router node on the map and have every interface under it get polled? I just want ORION to report the interface as a down if it can't get to it, is this possible?
