AP QoS DSCP value changing

Hi All,

Aruba is saying that from QoS point of view AP is keeping QoS setting comming from client.
But according to my experience client application is sending DSCP value 26, AP is receiving on wireless radio as priority 3 packet and then sending it on AP wired uplink as DSCP CS3.

DSCP 26 (client) -> priority 3 (AP radio) -> DSCP CS3 (AP wired uplink)


So as soon as client packet is encapsulated to GRE AP is changing DSCP value to CS3 even when original DSCP value was DSCP 26.


Is this expected behavior? By default is it always that AP is able to take only 3 most left bits from DSCP and those bits are placed to GRE so in GRE we are able just to get DSCPs CS1, CS2, CS3,...?
