6500 real life problem, I am going to go with dscp since the port-channel
has an ip.

devecchio,
Seems to me you could trust either, but DSCP makes more sense. Is this a
lab
problem or real life? 3550 or 6500? On 3550 all qos is physical port
level,
and ports in an L3 Po are still L2, and COULD be trunked/tagged.
Can you give more context?

Guys,
I am configuring a L3 port-channel to a distro and all members of this
portchannel are just standard gig interface with the portchannel command.
ON
a L3 portchannel, I have the ip configured etc. the command mls qos trust
dscp is to be used instead of cos due to it being a l3 port? Although the
switch will map cos-dscp vice versa it will not be expecting a cos value
on
a l3 port? The rule states if connecting to a router trust dscp/if a
switch
trust cos...I am guessing the rule still applies for switches as l2 port
channels and roulers as l3 port channels..
