I wanted to see what happens when you configure egress Qos with SRR. To accomplish this, I create a policy-map which set the DSCP 40 for WWW traffic.

ip access-list extended ACL_HTTP
 permit tcp any any eq www
class-map match-all CM_HTTP

 set dscp cs5
interface FastEthernet0/1
 description laptop
 mls qos trust device cisco-phone
 service-policy input PM_QOS
