Running LMS 2.6 RME 4.0.6

Hi all,

I'm trying to find a good way to create a group that specifies all of my CatOS switches. I've tried it a few different ways. No matter which way I try, the results only include about half of the devices that actually run CatOS. Here is the string I'm using:

Device.Image.Sys_Description contains "Catalyst"

If I grab a detailed device report for the missing devices the System Image Description field has the words "Catalyst Operating System". So I don't understand why the search isn't picking the devices up. Am I missing something here?

Thanks
