Re: NBAR usage?

Is there a limit as to how far you can use NBAR in conjunction with

this manner on a slow link like a T1 is okay, but shouldn't be done on
a 45mb DS3. Is that true? Does NBAR still allow CEF forwarding or
does it process switch everything?

From what I understand NBAR requires CEF to work.

performance depends mostly on what you are trying to match with NBAR
and which platform you are running on.
