a cosmetic change only, behavior stays the same.

Additional guidelines include:

If you rely on Class of Service (CoS), all interfaces should be tagged. None should be set to VLAN 0,
because that indicates they are in the native VLAN.

If you rely on CoS, switchports connected to the WLC should be trunk ports set with the mls qos
trust cos

 command.

• 

Switchports connected to local mode access points (APs) and Hybrid Remote Edge Access Point
(H-REAP)/FlexConnect APs with no locally switching Wireless LANs (WLANs) should be access
ports set with the mls qos trust dscp command.

• 

If you rely on CoS, switchports connected to H-REAP/FlexConnect APs with at least one locally
switched WLAN should be trunk ports set with the mls qos trust cos command.
