A have a 7600/SUP720 with an ES20 card that i want to be used to translate the outer vlan of a connection and apply some qos there.

vlan 3500/x -------------- vlan 3600/x
        6500 ---- 7600 ---- 6500


1) Will the following work?

7600/ES20
---------
interface GigabitEthernet5/0/0
  no ip address
  service instance 1 ethernet
   encapsulation dot1q 3500
   rewrite ingress tag translate 1-to-1 dot1q 3600 symmetric
!
interface GigabitEthernet5/0/1
  no ip address
  service instance 1 ethernet
   encapsulation dot1q 3600
   rewrite ingress tag translate 1-to-1 dot1q 3500 symmetric


2) If i want to terminate locally on the 7600 an inner vlan, can i use the following along with the above translation:

interface GigabitEthernet5/0/0.1301
  description ** test termination **
  encapsulation dot1Q 3500 second-dot1q 1301
  ip address x.x.x.x


3) What kind of egress QoS can i use on the main interface and on the subinterface? I did some tests but i wasn't successful.

7609#sh policy-map TR1

   Policy Map TR1
     Class class-default
       priority 1000 (kbps)
      police cir 5000000 bc 156250
        conform-action transmit
        exceed-action drop

7609(config-subif)#service-policy out TR1
Police and strict priority must be configured together for egress QOS.
priority kbps command is not supported in output direction for this interface
Configuration failed!


7609#sh policy-map TR2

   Policy Map TR2
     Class class-default
       Average Rate Traffic Shaping
       cir 50000000 (bps)

7609(config-if)#service-policy output TR2
Service-policy can not be applied to main interface when service-instances are configured.
