Looking to classify/mark with MQC/IP NBAR on ingress and CBWFQ on egress with following configuration, appreciate any feedback or input:

Hello,
The usage of QoS on the 7600 and the 6500 to a huge extent on the line cards being used.
Could you give me the output of show module and show version that is currently in use on the 7600?
7600 follows Catalyst QoS, and is implemented in hardware, which means most of the options that you have used here in the policy maps are not supported since they are part of the MQC QoS schema.
For further information refer to this link:
Implementatio of QoS also depends on the kind of line cards being used. ES+ line cards do support full MQC QoS.

looking at the SIP-400 capability, following should be possible supporting MQC marking and CBWFQ
•IP precedence (set ip precedence command)—Input and output
•DSCP (set dscp command)—Input and output
•Class-based marking
•DE to EXP marking/ToS/DSCP
•CLP to EXP marking/ToS/DSCP
•Ethernet 802.1q priority bits to EXP marking (EoMPLS)
•Access control lists (IPv4 and IPv6)
–Access group (match access-group command)—Input and output
–Address (IPv6 compress mode only)
–Name
–Number
–Source and destination port
–TCP flag (IPv4 only)
•ATM CLP (match atm clp command)—Input ATM interface
•Configurable queue size
•CoS (match cos command)—Input and output dot1q tagged frames for 2-Port Gigabit Ethernet SPA only
•Frame Relay DE (match fr-de command)—Input Frame Relay interface
•Inner CoS (match cos inner command)
•IP DSCP (match dscp command)—Input and output
•IP precedence (match ip precedence command)—Input and output
•MPLS EXP (match mpls experimental command)—Input and output MPLS interface
•Multiple matches per class map (up to 8)
•CBWFQ
•Per-VC CBWFQ
•DSCP, EXP and Precedence matching
•LLQ or priority queueing (strict priority only)
•Dual-priority queuing
