Aeros Qos/AVC with Flex connect

[scottbreslin]

Hi,

I am trying to implement AVC/QoS for MS-Teams.  This is in a lab environment at present prior to being deployed on customer environment.

The lab WLC is a vWLC running version 8.10.196 and the AP is a 2802.

The AP is operating in FlexConnect Mode with a locally switched WLAN. 

I have a FlexConnect AVC profile configured which contains the following markings:

The profile is mapped to the QoS within the WLAN:

The AP is also a member of a FlexConnect Group where the AVC profile is also mapped:

The switch port to which the AP is conencted, is configuted as a .1q trunk and set to trust DSCP:

interface FastEthernet0/6
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,942
switchport mode trunk
mls qos trust dscp
spanning-tree portfast
end

Checking the interface, I also see DSCP 34/46 incoming:

LABSW01#show mls qos interface fastEthernet 0/6 statistics
FastEthernet0/6 (All statistics are in packets)

dscp: incoming

5 - 7 : 0 3523

However, when i check the AVC monitoring for a connected client (Within Flexconnect>Groups>Client>Application Statistics the DSCP values for in/out are 0/0:   

Therefore, is there something wrong with my configuration/setup as I assumed that I would see the DSCP in/out values as they arrive from the AP and then as they are then re-marked using the AVC profile.  

Would some please assist as i'm unsure as to whether the QoS is actually working or not.

Thanks

I can't see anything specifically covering that in the documentation so I suspect it's just a limitation of flexconnect local switching.

Must be then. Thank you for taking the time to research and reply.

 As per Cisco doc:

"AVC on locally switched WLANs is supported on Second-Generation APs."

 I believe you need to use at least 3X00 AP. (3600, 3800)
