Codel traffic shaping / Queue adding possible at all?

[kammerjaeger]

Hi,

how does the Codel traffic shaper work? Every time I select it in the gui, I cannot add any queues any more. In addition already added queues vanish.
If I select Codel in a hsfc queue under "Scheduler options" it is not saved.
Has anybody worked out how this works?

Best regards,

EDIT:
I now tried to add queues manualy, it is not working at all!
I used the wizzard to create a base configuration (HFSC), then I wanted to add a queue with extra low priority for the syncronisation of two serve.
After adding it with "Add new queue", changing the values to:

Queue Name: qServerSync
Priority: 0
Scheduler options: Explicit Congestion Notification
Bandwidth 100Kbit
Service Curve (sc):  Link: m2 100Kb

I saved the queue with save. Afterwards it just vanished, I cannot see it anywhere under "Firewall: Traffic Shaper". Any idea?

I am using 2.1-RELEASE 64Bit
