Hi David,

thanks for your quick reply.

The dictionary:

ATTRIBUTE       WiMAX-QoS-Id                            29.1    byte

ATTRIBUTE       WiMAX-Media-Flow-Description-SDP        29.16   string

One of my QoS flows:

Since I get good results if I use only one QOS profile, I assume that I
can skip attributes and that I'm not required to use them all.
(Please correct me if I'm wrong.)

And this is the part that I do not understand:

If I continue by using a second QoS profile:

>         WiMAX-Schedule-Type+=2,

I expected freeradius to see that WiMAX-QoS-Id is an element of a new
tlv. And then create a new WiMAX-QoS-Descriptor for it. (Instead of
combining the data for the two QoS profiles into one WiMAX-QoS-Descriptor.)

Is my ASN violating some standard by not accepting one
WiMAX-QoS-Descriptor containing data from two QoS profiles?

If that is the case, is there another workaround beside putting
something between the two QoS profiles? (This is what I did by adding
"Acct-Interim-Interval+=60".)


Thanks,
best regards,
Sven
