Packets don't get marked when we configure service-policy input qos-map on the interface which traffics comes from (g3/1). If we however configure service-policy output qos-map on our layer 3 vlan interface (vlan 698) we can see the right DSCP marking. (This is verified with Ethereal on a laptop connected to on the downstream 10.105.1.33 C6509 switch)
We want to mark all 192.168.1.0/24 traffic coming from g3/1 to be distributed downstream on vlan 698. How come it doesn't work on ingress interface? Or is it enough to just have the service-policy output on the egress interface?
This is the working configuration:
mls qos
!
class-map match-all qos-class
match access-group name qos-acl
!
policy-map qos-map
class qos-class
set dscp af42
!
interface GigabitEthernet3/1
