C6500 QoS - Link between Internal DSCP and CoS value
there is something I find strange on C6500 about QoS: C6500 derive an internal DSCP value for it's internal use, but when configuring the qos mapping on output interfaces, only a cos value (I guess, an internal cos value) can be used. Is it a misunderstanding from me, or is it really illogic?

6500s do map DSCP into internal CoS values. I suspect this might be both because it works nicely with L2 CoS and/or L3 IP Precedence. I.e. it may have been quite logical at the time the 6000/6500 series were first designed.
