Hi All,
I am having issue specifally doing QOS configuration on 6503 or 6524 or 6509 switches. I am unable to match any EF(voice) traffic for eompls(vlan based) on 6503 cisco switch. If i use any other router as 2811 or 2821 my QOS configuration works perfect but if i put 6503 as PE2 it does not work.i am using vlan based eompls.
Below is the scenario & configuration which i am having issue.
CE1(2821 router)(dot1Q)--------->PE1(2821 router)------->P(6524 switch)-------->PE2(6503 switch)------->(dot1Q)(2821 switch)CE2.
On CE1 i can match ip-precedence 5 traffic and mark that traffic to cos5 on outbound port.On PE1 i can match cos5 packet and mark with mpls exp top5 on inbound port, on outbound port i can match mpls exp 5.
On PE2(6503) i am unable to match that mpls exp5 packet on inbound port. none of the configuration worked on 6500 series switches with mls qos, ,mls qos trust dscp,mls qos trust cos etc. Although i can match cos5 traffic on CE2 on inbound interface.i can not match mpls exp 5 traffic on 6503 and all i can see traffic as default-class on 6503 switch. I tried many things and many configurations on 6503 but nothing worked.If i put 2821 router as PE2 instead of 6503 my qos configuration works. but why if i put 6503 my same qos configuration does not work?

Can anyone tell me how qos works on 6500 series switches or where i am having issue in my scenario.
i am using this ios on 6503: s72033-advipservicesk9_wan-mz.122-33.SXI3.bin.
below r my questions for 6503 qos:
1.do i need to use some other map tables,am i using correct map tables on 6503 as cos-dscp,dscp-cos,exp-dscp etc.
2.any other configutaion of qos needed on 6503?
3.i am unable to match anything on outbound port of 6503.
4.on 6503 i am using sup720 and PFC3BXL.any specific configuration needed for PFC3bxl.
5. 6503 not allowing me to match qos-group on inbound interface, not allowing me to set cos5 on outbound interface. not allowing me to set cos5 as an inbound interface.
