QOS & WMM

[lgontars]

Hi,

I have a question about wireless WMM.... looking at a paper about it, the paper talked about 802.1p tagging... doesn't this assume that WMM is being used on a host that is trunking?

Also, i read that WMM & DSCP qos on the AP can't be enabled at the same time?

Thanks!

Lisa, the dot1p tagging is on the dynamic interface of the controller. The wmm is on the client IF the client supports it

snippet:

Configuring QoS Enhanced BSS (QBSS)

You can enable QBSS in these two modes:

•Wireless Multimedia (WMM) mode, which supports devices that meet the 802.11E QBSS standard

and also:

The WLAN QoS level (platinum, gold, silver, or bronze) defines a specific 802.11e user priority (UP) for over-the-air traffic. This UP is used to derive the over-the-wire priorities for non-WMM traffic, and it also acts as the ceiling when managing WMM traffic with various levels of priorities. The access point uses this QoS-profile-specific UP in accordance with the values in Table 6-1 to derive the IP DSCP value that is visible on the wired LAN. see chart on the url too
