I'm trying to rewrite all traffic to 0 coming in on a etherchannel. This is how the config looks like.
When I do RSPAN and capture traffic for one of these VLANs I can still see DSCP flags set to something other then 0.
class-map match-all rewrite
match access-group name rewrite-dscp
!
policy-map rewrite
class rewrite
set dscp default
!
ip access-list standard rewrite-dscp
permit any

service-policy input rewrite
end
I can't set the service policy command directly on the physical interfaces so that's why its not there.
router(config-if)#service-policy input rewrite
Policy can not be installed because interface GigabitEthernet2/35 is a member of Port-channel
MQC features are not supported for this interface

You should configure the port-channel and physical ports with the command 'mls qos vlan-based', and then configure or apply the service-policy rewrite on each of the trunked vlan interfaces (SVIs) as shown below:-
!
interface port-channel 3
mls qos vlan-based
!
interface GigabitEthernet2/35
mls qos vlan-based
!
interface GigabitEthernet2/36
mls qos vlan-based
!
interface vlan 101
service-policy input rewrite

.
interface vlan 179
service-policy input rewrite
