Now that NBAR is supported on this supervisor, can anyone tell me what performance issues I will experience by enabling IP CEF and IP NBAR, since, according to thsi article the only way it can be done is via software only. Will enabling CEF/NBAR make a negligible performance hit on the CPU or is this something I need to be very concerned about.
Thanks for the resposne. How would one go about determing the amount of memory requried before turning on IP CEF ? I can see where this would be important since you could potentially crash a router by turning on cef if it doesn't have appropriate memory, right? Any suggestions on how to determine CEF memory requirements for a router?
Also, don't the MSFC's and PFC's use IP CEF by default?
