Ah, of course, I failed to actually read what you had wrote about the
queueing and focused on the DSCP trust. :-)

It seems you were right all along, incoming priority-queue on the 6500
can only work if packets arrive with 1p-bits, or if the card happens to
be a WS-X6708-10GE which has the "priority-queue dscp-map ..." command.

(The 6708 _is_ a sweet card regarding QoS, at least among LAN cards.)
