QOS & WMM

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!

Re: QOS & WMM

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

http://www.cisco.com/en/US/docs/wireless/controller/4.0/configuration/guide/c40wlan.html#wp1087878

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:

http://www.cisco.com/en/US/docs/wireless/controller/4.1/configuration/guide/c41wlan.html

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
