 The response is a packet with class/type pairs. One frame can hold a maximum of 256 pairs. If more is needed send multiple frames. Type can be set to zero to indicate ALL types of that class.

 A node that is interested in everything just send a [CLASS2.PROTOCOL, Type=41 (Get event interest response)](./class2.protocol.md#type41) with no data if asked to provide that information.
