I have a class that has a Device specified (such as Main or Upper_LEM). When I try to create a child class of this class, I get the following error message:
Matching rule incompatible with Parent class
I can create the class directly under /Inbound, but when I try to move it down below the device-based class, I get the same error message.
When you are using device-based classes, the child classes must have the same Device selected (Main, Upper, Lower, Left, Right) in the matching rule, otherwise the rule will not be compatible with the parent.
