I haven't seen any response to this post, so should I conclude that there is no objection to resolving this comment as: REVISED At the end of 9.4.2.30 add: A classifier classifies on the basis of at least one match. NOTE---For example, when the Classifier Mask field is present and not reserved, at least one bit of this field that is not reserved is set to 1. ? Thanks, Mark --

Mark Rison I was asked to start a thread on this comment:
As far as I can tell, the classifiers have the following classifier masks: 0, 1, 2, 4, 5: bitmap indicating parameters that need to match 6, 7, 8, 9: bitmap with 2-bit subbitmaps 3: reserved 10: not present (despite what Figure 9-364—Frame Classifier field format says -- see CID 1856) The direction of the group was to specify that classifiers that don't classify anything shall not be transmitted, rather than trying to specify that they never or always match. Because there are so many classifiers, and they classify in quite significantly different ways, I propose adding this general statement at the end of 9.4.2.30: A classifier classifies on the basis of at least one match. NOTE---For example, when the Classifier Mask field is present and not reserved, at least one bit of this field that is not reserved is set to 1. Thanks, Mark --
