ES20+ line card QoS ... mls QoS

Would like your assistance please regarding ES20+  QoS

As I understand for these cards QoS is MQC; i.e. similar to that of normal WAN cards

1- If i have 7600 with ES+ card only then I dont need to configure global command "mls qos" and the concept of trust boundries "mls qos trust dscp" will not exist , correct ?

||||

2- For below output, why "show mls qos queuing" is giving an O/P similar to that of WS-X6xxx LAN modules

Also why it is WRR when scheduling is not configured

I expected that command will not work with this module as it is similar to WAN modules

7606-1#sh mls qos queuing in gi1/5

Weighted Round-Robin

  Port QoS is enabled

  Port is untrusted

  Extend trust state: not trusted [COS = 0]

  Default COS is 0

7606-1#

Thanks

Another strange thing

when mls qos is enabled

7600-PE1#sh mls qos queuing interface te2/1

Weighted Round-Robin

  Port QoS is enabled

  Port is untrusted

  Extend trust state: not trusted [COS = 0]

  Default COS is 0

7600-PE1#

when mls is disabled

7600-PE1#sh mls qos queuing interface te2/1

Weighted Round-Robin

  QoS is disabled globally

  Trust state: trust DSCP

  Extend trust state: not trusted [COS = 0]

  Default COS is 0

7600-PE1#

Any explanation please

Thanks
