Looking at the qos statisctics for the port gi1/0/1 I noticed that for web browsing (proxy port 8080) no packets appear in dscp 10 (AF11) in the outgoing dscp statistics. DSCP field should be rewrite to AF11 instead of DSCP 0 (for web browsing) because of Class-map CM_BULK-DATA & ip access-list ACL_BULK-DATA. Right or wrong ?

I don't understand why. What is my mistake ? your help would be greatly appreciated. Thank you.
