IS there any way to see the queues/cos mapping etc on the Sup6E
eg the old commands were "show qos map". Is there any way to configure and show what DSCP's go to certain queues?

Hi,
There is not a default mapping like the "old".
In Sup6E the Qos has changed to MQC, like routers. The default behavior is to trust the qos recived and only a default queue.
From the maunal....
By default, in Supervisor Engine 6-E, without any service policies associated with a port, there are two queues (a control packet queue and a default queue) with no guarantee as to the bandwidth or kind of prioritization. The only exception is that system generated control packets are euqueued into control packet queue so that control traffic receives some minimum link bandwidth.
The MQC model does not support the trust feature, which is available in the switch qos model on Supervisor Engines II-Plus through V-10GE. In the MQC model supported on the
Supervisor Engine 6-E, the incoming traffic is considered trusted by default. Only when the
trusted boundary feature is enabled on an interface can the port enter untrusted mode. In this mode, the switch marks the DSCP value of an IP packet and the CoS value of the VLAN tag on the Ethernet frame as "0".
Se the manual for futher information.

Hi,
yes there is a way ==> MQC. If you apply auto qos then you'll see the Q mappings and the remarking actions. Looks like that:
class-map match-all Skinny-QosGroup24
match qos-group 24
class-map match-all VoIP-QosGroup46
match qos-group 46
class-map match-all Skinny-Dscp26
match dscp af31
class-map match-all VoIP-Dscp46
match dscp ef
class-map match-all Sinny-Dscp24
match dscp cs3
class-map match-all VoIP-Cos5
match cos 5
class-map match-all Skinny-Cos3
match cos 3
!
!
policy-map in_Trust_COS
class VoIP-Cos5
set qos-group 46
class Skinny-Cos3
set qos-group 24
policy-map in_NO_Trust
class class-default
set dscp default
set cos 0
policy-map in_Trust_DSCP
class VoIP-Dscp46
set qos-group 46
class Skinny-Dscp26
set qos-group 24
class Sinny-Dscp24
set qos-group 24
policy-map out_QOS
class Skinny-QosGroup24
set dscp cs3
set cos 3
class VoIP-QosGroup46
priority
set dscp ef
set cos 5
class class-default
dbl
set cos 0
set dscp default
==> you can also configure trust state of ports..
hope this helps
