Please post us your show class-map, show policy-map and show run int x/x
to see how your class-maps are defined, policy-maps and how you are applying
it.

Also, Do you have IP CEF enabled globally? without it it will not work.

P.S.: Brian, is that monkey talking on the microphone? :) I think everybody
gets spam like that at work all the time. we do. I wouldn't quite put it in a
time killer though.
If someone wanted to waste time, there are whole realms dedicated to progress
your boredom. e.g.: bored.com

        I have entered this exactly, and still things hit the default-class for some
        reason. Is it because I also have nat on the router ? Does that affect the
        configuration someway ?

        Try this:

        Voice_GW_LAB#sh run class-map
        Building configuration...

        Current configuration : 81 bytes
        !
        class-map match-all youtube
         match protocol http host "*youtube.com*"
        !
        end

        Voice_GW_LAB#sh run policy-map
        Building configuration...

        Current configuration : 59 bytes
        !
        policy-map BLOCK-youtube
         class youtube
          drop
        !
        end

        Voice_GW_LAB#sh run int f0/1
        Building configuration...

        Current configuration : 234 bytes
        !
        interface FastEthernet0/1
        ...
        service-policy output BLOCK-youtube
        end

        Voice_GW_LAB#

        Voice_GW_LAB#sh policy-map interface f0/1
         FastEthernet0/1

         Service-policy output: BLOCK-youtube

           Class-map: youtube (match-all)
             27 packets, 29642 bytes
             5 minute offered rate 0 bps, drop rate 0 bps
             Match: protocol http host "*youtube.com*"
             drop

           Class-map: class-default (match-any)

               Hi there, I was just doing a lab and thought I would try something on
my
        test
               DSL connection.

               My intent was to block www.youtube.com with QOS

               Here is what I have ...

               !
                class-map match-all YOUTUBE
                match protocol http url "www.youtube.com"
               !
               !
                policy-map CBWFQ_SHAPE_OUT
                class YOUTUBE
                 drop
               !
               !
               interface Ethernet0
                service-policy output CBWFQ_SHAPE_OUT
               !

               But for some reason, it doesnt work. I have CEF enabled. When I do a
show
               policy-map int e0, it shows everything hitting the default
class-default

               I am sure I am missing something simple, but my QOS skillz are low and
am
               trying to build them. Thanks !
