Determines whether interface role associations are subject to loose or strict capabilities verification. Setting the value of this attribute to 'roleAssocCompatLoose(1)' means that interfaces with different capabilities may be associated with the same role. In this case, configuration issues may arise due to these differences. Setting the value to 'roleAssocCompatStrict(2)' means that only interfaces with compatible capabilities may be associated with the same role. This mode can be used to avoid configuration issues resulting from the interfaces assigned to a role not having the same underlying capabilities.
