Question: how do you know whether a particular NAS device supports all of
the syntax covered in the NAS-Filter-Rule? For example, a layer 2 switch
might only support layer 2 filters, or a NAS might only support layer 3
filters. A unified syntax makes sense, but allowing layer 2 and layer 3
filters to be included in one attribute implies that devices have to
implement both layer 2 and layer 3 filters. If a device only supports
part of the syntax, there is no easy way for it to advertise that.
Or is support for both layer 2 and layer 3 filtering common enough at this
point that we don't need to worry about this?
