Best explanation so far Gladstone thanks.... As you
picked up on I was looking for various ways that it is
possible to set DE for whatever reason ,weather or not
it is considered best practice wasnt of a concern ,
just looking for methods to set DE what IOS features
are available to tag desired traffic with DE if the
requirement ever came about . So exactly what you
stated that MQC with 12.2T could be used as well as
FRTS... Thanks a bunch
