[c-nsp] Scheduling and queuing capabilities of port channel interface

[LEMOINE Jean-marie]

Hi,
 
I am trying to configure QOS on channelized GigabitEthernet ports on a
cat6500/sup2-msfc2.
Ios is s222-adventerprisek9_wan-mz.122-18.SXF5.
Giga card is WS-X6408A-GBIC
 
I am able to map a frame COS value to an egress queue (the priority queue)
on the physical gigabit ethernet interface.
but no way to add the wrr-queue cos-map command on the port-channel
interface.
 
and anyway :
 
sh interface giga 3/2 capabilities : 
QOS scheduling:        rx-(1p1q4t), tx-(1p2q2t)
 
sh interface po3 capabilities :
QOS scheduling:        rx-(1q4t), tx-(1q4t)
 
Am I wrong trying to configure qos on channelized interface ?
Any way to achieve that ?
 
Do I have to upgrade to 10gig interface ?
Any clue ? :-p
 
Thank you for you help
