ANY queueing is for traffic leaving the router. (Although presumably, it
entered the router at some point!)
CQ is all about queuing. So there's no direction specified, but it is
outbound only.
MQC is about many different things. But if you use the "bandwidth" or
"priority" commands, which are the queueing command sets for MQC, your
policy-map then can only be applied in an outbound direction. The router
will yell at you otherwise. ;)

Subject: QOS: choosing CQ or MQC
I've been working my way through the IPExpert labs. One of the labs has a
QOS task that states "Configure a queue for traffic flowing over R5's serial
interface". So I could be configuring CQ or MQC for this task. My concern
for this type of question is the "traffic flowing over" wording. It seems to
imply traffic in both directions. I've been reading over the DocDVD and it
seems to me that queuing only affects traffic outbound from the router,
regardless of whether you use MQC or CQ, so either can be used in this
situation. Correct?
My confusion stems from the fact that MQC must be applied inbound or
outbound whereas CQ does not have a direction associated with its
configuration. Originally I thought this meant CQ worked for traffic coming
into and out of the interface, but on reflection I now think it only works
for traffic leaving the router. Correct?
Thanks in advance,
Ash.
