I'm looking for a solution to implement a CBWFQ QoS on, and I need to implement it on an egress 4Gbps bundled Giga-Ethernet in one port-channel

But I can't find a suitable platform or router that support such feature, any advise to choose a one ??

I had my research, and I had found a good platform for us, and it's Cisco ISR 3945 with an enhanced either-switch module (SM-D-ES3G-48-P), but I'm not sure that the SM-D Etherswitch would support such a feature,
does anyone have the answer if it can support such a scenario?

the policy will be as the following:

class-map match-any MATCH_DSCP_512XK
match dscp 50
class-map match-any MATCH_DSCP_1XM
match dscp 51
class-map match-any MATCH_DSCP_2XM
match dscp 49
class-map match-any MATCH_DSCP_4XM
match dscp 48
class-map match-any MATCH_DSCP_8XM
match dscp 63
class-map match-any MATCH_DSCP_1SM
