Interface ${Interface.Caption} for node ${NodeName} is ${Interface.Status}.
gives "Interface X - Node x - for node X is 1 ." or "Interface X - Node x - for node X is 2 ."
The status is not showing as Up or Down, just 1 or 2
You would think the default/canned message would work...
Try removing the . (dot) between ${InterfaceCaption} and use ${Status} for the interface status.
Well that didn't work (removing the dot).
But, changing to ${Status} did work.
