Thanks for the info!
I took a look and noticed that even the list includes MQC-Based Frame
Relay Traffic Shaping and Class-Based WRED, if you go to the linked
pages from this page, CEF is not mentioned in those features themselves?
Anyone knows why?
thanks

That is a cool link - thanks for sharing!
I have yet to see a QoS feature that requires Cisco Express Forwarding
(CEF) to be DISABLED.
In fact - I know of candidates that turn on CEF everywhere to start
their lab as part of a "base" configuration that they apply to all
devices. This configuration also includes things like aliases and other
nifty shortcuts.
I never bothered with such a file or such an approach to CEF - I just
learned where it was required and enabled it when I came upon such a
task. Of course, sometimes the IOS is nice and actually tells you that
you require it....but I would be cautious about relying on that.

Hi GS,
There is some relation between these two and my question is when should
we
enable CEF and when not to while configuring QoS. The following link
gives
some details on it.
Example: class-based QoS features are supported only on routers that run
CEF
.

Any specific features that require CEF to be disabled?
Thanks for your help.
Cheers..Ken.
