QoS on PIX 7.2 for voice and video

Unanswered Question
Jan 30th, 2007

I have the below a couple of questions about the below configs.

1.

Policy-map OUTBOUND

class Voice

priority

service-policy OUTBOUND interface outside

Will the priority command under the policy map enable a packet under this specific class to have priority over the maximum amount of traffic or only 75%? Is there a percent of the bandwidth that is dedicated to best effort traffic?

2.

Policy-map OUTBOUND

class Voice

priority

class Video

priority

service-policy OUTBOUND interface outside

will only the first packet that arrives (Voice) receive priority and the next next packet (Video) only receive priority after the first packet is transmitted.

3.

Is there a recommended config for handling delay sensitive traffic like Voice? Is the priority-queue recommended? If so what parameters should be used? Same for Rate limiting.

TIA

I have this problem too.

Along a similar topic, I'd like to prioritize UDP traffic for a network game on port 27666 (legit; I work for a developer making multiplayer games :P) to prevent packets dropping and latency spikes when people are using the internet for things like ftp/web etc.

Can my 5500 do this? I've googles for how-tos, but not found anything yet.
