DSCP maps in Catalyst

I am trying to set up a number of different scenarios with setting dscp
values on a router and reading them on another. This works quite
well......

R6 - - - - - - - CAT2 - - - - - - - R2

R6......
Setting the dscp of ping traffic to R2 with a policy map (set to dscp =
63)

R2.....
Set up an inbound access list on R2 .....access-list 140 permit ip any
any eq dscp 63 log-input

This works. However, I am trying to get the CAT2 to change this dscp
with a mutation map and can't seem to get this to work properly. Any
ideas......

Cat2 configuration on the switchport connected to R6......

Cat2#sh run int fa0/6
Building configuration...

Current configuration : 200 bytes
!
interface FastEthernet0/6
 switchport trunk encapsulation isl
 switchport trunk allowed vlan 20,40
 switchport mode trunk
 switchport nonegotiate
 mls qos trust dscp
 mls qos dscp-mutation NEW
end

Cat2#sh mls qos map dscp-mut

   Dscp-dscp mutation map:
   NEW:
     d1 : d2 0 1 2 3 4 5 6 7 8 9
