An index assigned for each type of redundancy group supported on a managed system that requires its own table listing entPhysicalVendorTypes allowed as members for its groups. For instance, port groups have a different set of allowed entPhysicalVendorTypes than linecard groups. So each should have a separate ceRedunGroupTypeIndex. For this example, a command line interface may differentiate by using separate keywords (port-group versus linecard-group) rather than exposing the ceRedunGroupTypeIndex to a user.
