Thats right, if the QoS is globally disabled on the switch, It will not
touch the COS or DSCP markings. You'll need to issue:
"no mls qos" on CAT3550
"set qos disable" on CAT6500
However look carefully at what the lab wants you to do. You may need to
create a policy in the MQC that will mark packets that go into the
routers from the switches using either NBAR or ACLs to classify the
traffic. Otherwise, the LLQ on serial interfaces may fail because
packets aren't properly marked by the originating device.

Hello All,
What is the best approach to make sure that my switches are not going
to mark or remark any packets coming and going to the endpoints ?
Am I safe if I just configure the vlans on the interfaces and let the
qos off ?
Thanks in advance.
