We have several Dell 6200 series switches running 3.3.5.5. We are putting in several Avaya G430 Gateway units at various locations and are attempting to configure the switches to utilize Class of Service Queing in order to handle DSCP 46 class 5 traffic marked with hi priority.
Part of this process is setting up 3 laptops with the ability to generate simulated VOIP traffic to and from each site. To date, we haven't been able to get a good clean test and it's as if our COS settings are not applying. We've mapped the Class 5 to Hardware queue 6 and also mapped DSCP to queue 6 within the DSCP mapping table. We've also configured STRICT priority globally on all interface for que 6.
In general, we have 3 VLAN's that are setup to route between one another as well as site to site. What could I be missing? Are there any other mechanisms within the switches that would supersede the COS settings?
