Hey, ive been trying to get a simple QoS Implementation to work. we purchased a stack of 3850s for incoming traffic from clients. so ive been trying to marking incoming packets from the client network with specific DSCP and then apply priority based on those DSCP values. it doesnt seem to be marking anything thus making the outbound policy-map restrict have lots of output drops.
what am i missing here?
so its:
client -----------> ( g1/0/23 .core. g1/1/4) -------> MPLS Link
!!!! creating ACLs/Class Maps for traffic
ip access-list extended priority_mark_voip
permit udp any any range 5000 65535
ip access-list extended priority_mark_data
permit tcp any any eq www
permit tcp any any eq 443
permit tcp any any eq 4172
permit udp any any eq 4172
class-map match-any priority_Data
match access-group name priority_mark_data
class-map match-any priority_voip_marking
match access-group name priority_mark_voip
!
class-map match-any client_traffic_data
match dscp cs2
class-map match-any client_traffic_voip
match dscp ef
!!!!!! policy-Map for incoming traffic
policy-map classifying_traffic
class priority_voip_marking
set dscp ef
class priority_data_marking
set dscp cs2
!!!!!!!! policy map for outging traffic
policy-map priority_traffic_prod
class client_traffic_voip
priority percent 50
class client_traffic_data
priority percent 40
policy-map port_child_policy
class non-client-nrt-class
bandwidth remaining ratio 10
!!!!!!!!!! applying Policy-MAPs
interface g1/0/23
service-policy input classifying_traffic
interface GigabitEthernet1/1/4
service-policy output priority_traffic_prod
!!!! show policy-map show no packets being marked/classified.
GigabitEthernet1/0/23
Service-policy input: classifying_traffic
Class-map: priority_voip_marking (match-any)

Tomas,
are you accesslist that define your intersting traffic getting hit?
do sh ip access list priority_mark_voip for instance
Looking at the default traffic there is traffic getting passed on the service-policy input classifying_traffic
Please rate if useful

i dont see any hits, but the traffic coming into the g1/0/23 is pretty much what its coming from the client, (RTP traffic and WMview traffic) is what i put in the ACL.
show access-lists priority_mark_voip
Extended IP access list priority_mark_voip
80 permit udp any any range 5000 65535
show access-lists priority_mark_data
Extended IP access list priority_mark_data
80 permit tcp any any eq www
90 permit tcp any any eq 443
100 permit tcp any any eq 4172
110 permit udp any any eq 4172
