qos on catalysts

Hello,

I'd like to have some info about the marking on the 6500 with an MSFC:

The edge device marks the traffic with Cos=5 & DSCP=46, the traffic pass through some 3500 XL switches. I trust the Cos on all the interface of both switches. Can I use "no trunk" links between the switches and trust the Cos, or am I obliged to use 802.1q trunks?

Another question:

The traffic arrives at the 6500 and must be routed to another vlan. What happens with the marking? Does it occur automatic mapping between Cos and Dscp before the entering into the msfc? And is there an automatic mapping Dscp-Cos before sending the packet to the egress port?

Thansk for your infos
