Thanks for the example. Most of the attributes are already in Radiator's
dictionary but do you have documentation about the ones starting with
Alvarion-?

Google finds something, but if you have a definitive source, please let
us know.

Already in dictionary

Would need the definitions for the above two.

These all are carried within WiMAX-Packet-Flow-Descriptor and are
already in dictionary. The names are a bit different, no WiMAX prefix in
Radiator's dictionary. Look for WiMAX-Packet-Flow-Descriptor in
dictionary and the above are defined there.

With Radiator you would do something like this:

AddToReply WiMAX-Packet-Flow-Descriptor =
"Packet-Data-Flow-ID=1,Direction=Bi-Directional,Transport-Type=IPv4-CS,Uplink-QOS-Id=1,Downlink-QOS-Id=1"

That's a static configuration in a configuration file, but you can of
course store this e.g., in a SQL DB.

Additional twist is there's also WiMAX-Packet-Flow-Descriptor-V2 which
is defined by a later WiMAX docs and looks similar but has a different
type value :(

The docs should tell which one is needed.

Would need the definition for this Alvarion attribute too.

These all are carried within WiMAX-QoS-Descriptor similar to
WiMAX-Packet-Flow-Descriptor.

I think the support in Radiator is already there and we just need to
find out what the Alvarion- attributes are.

Thanks!
