We are looking at enabling WMM and configuring mapping of DSCP traffic to the 4 WMM classes in a controller based environment, where all SSIDs are tunnelled.
We are marking traffic on all wired access ports including AP ports, and the ports connected to the controller are configured to trust DSCP markings.
I have a few questions:
- Is this a valid approach? We're assuming that the AP will include the DSCP info in the GRE header which will allow the traffic to be classified all the way to the controller, and out of the controller.
- How does WMM traffic management shaping work with multiple SSIDs?
If each profile has to add up to 100%, how does this affect the bandwidth available on other SSIDs and how is this calculated?
- Are there any other caveats with WMM on multiple SSIDs?
