[c-nsp] Ingress QOS marking and Multicast Replication Mode

[Андреев Андреевич]

Hi List,

there is one simple question - is ingress dscp marking works with 
Egress Multicast Replication?
I have 6500 box WS-SUP720-3BXL running 12.2(18)SXF17b IOS.

Input interface is located on WS-X6748-SFP card.
I have policy-map on it to remark multicast traffic dscp to 46 and 
then i need PFC to rewrite output COS values based on dscp.

Receivers who connected by routed ports see right dscp values.
But if output interface is switchport receivers see traffic with 
802.1p=0 and dscp=46.

Our aggregation layer cant do queuing based on dscp values so we have 
problem when multicast traffic leave this box on trunk links with 
802.1p=0;
Receivers are located at WS-X6748-SFP, WS-X6748-GE-TX and 
WS-X6704-10GE layer ports.

Is Ingress Replication Mode solve this issue?
And is there is any side effect?

Thank you.
