Anyone happen to know if any of the ASA 5500 series models support traffic shaping? I have a 5505 and it does not appear to.

The scenario here is that I need to ensure low latency for VoIP traffic over a broadband link with an upstream bandwidth of 512kbps. I am aware of the 5505's priority queue option but do not think that will help in this configuration as there would never be enough traffic to form queues on the 5505 but there could easily be outbound congestion on the dsl modem. I figure the only work around for this model would be to use the police option and rate limit everything except VoIP traffic to 512kbps minus my max. required bandwidth for my VoIP calls but this would be kind of an inefficient use of bandwidth.

Yes it does .

You can configure bandwidth limiting by the use of access-list policy map and class map .

If you need suggestions please let me know

Hey thanks for the reply. If you could give an example I would really appreciate it. Lets say I wanted to shape all outgoing traffic on my outside interface to 512kbps and give RTP (port 5001) traffic priority how would I do that?

I should have also mentioned I am running v8.0. I have checked through those documents before and appears the unit only supports policing, no shaping at this time.
