hi all,
we have a network connecting user and Datacenter(please find the attached network diagram), we want to implement QoS on the network, our plan is on the Data center Switch, we only mark the traffic from the server 10.1.1.10 with TCP port 8080 as DSCP value AF23, and let the router to shaping the marked the packet before sending out to user.

this is the config:


Data center SW(only part of configuration):

mls qos
no mls qos ip rewrite dscp
ip access-list extended Server8080
permit tcp host 10.1.1.10 eq 9090 any

class-map match-all Server8080
match access-group name Server8080

policy-map Marking_Policy
class Server8080
  set ip dscp af23

int g0/1
mls qos vlan-based
int g0/2
mls qos vlan-based

int vlan 10
ip addr 10.1.1.1 255.255.255.0
service-policy input Marking_Policy



when we capture the traffic @ rotuer, we found the traffic DSCP value still set to zero.
when we show policy-map int vlan 10, we found out that there is no traffic matching the class-map Server8080.

can someone tell me where is the problem and how to fix the problem?

thanks

Your problem is an incorrect ACL.  You are wanting to match traffic sent over TCP 8080, but your ACL is matching on 9090.




ip access-list extended Server8080
permit  tcp host 10.1.1.10 eq 9090 any
