We will deploy a wireless based network for our new plant soon.

most of the users will use wirless instand of wire cable except servers.

all the phones will use wireless also (Cisco cius)

Here is my question.

How can we setup QoS on wireless enviroument?

Baed on a tech note comes from Cisco:

mls qos turst dscp - on the switchport which connecto to AP.

but how about the switch port connect to WLC?

how can we allow high priority  traffic send out first, I mean from wireless user side.

(over 20 users per AP, how can I allow phone send out first)

many thanks and have a nice day.

Hi, Ton V

I read this article. one thing confused me.

Looks it seperate vlans by priorty traffic, but we usually put all the wireless client in a big vlan domain.

we have a QoS policy-map in our network end-to-end. so all the traffic into wlc should be marked already.

The big thing is how can we mark the traffic from AP to WLC? and allow AP accept high Q from wireless cilnet first instand of bulk traffic?
