Jeff,
The CEF switching path is what Cisco recommends for everything.
There were bugs early on. I don't think there are any functions where
they'll officially say to not use CEF. A TAC engineer may tell you to
turn it off for one reason or another, but where they do, you can be
sure it's a bug that they're working to resolve. CEF is also what is
implemented in the hardware forwarding ASICs of all the layer 3 switches
also. 99.9% of the time you're safe (and better off) turning it on.

Hello,
I know that there are some ramifications to enabling CEF. Of course you
need to enable it when you want to use NBAR.
But I also understand that enabling CEF will have some consequences, and
cause some other functions to stop working.
Can anyone fill in the blanks?
Thanks.
