RE: PBR on 6509 cpu utilization

Ok - low latency - is not trading - its also "cpu <40%" in my world as well :)

Joseph,
the world is not all low latency :)

But the 6500 is basically a switch, and even the sup720 can not drive all the port bandwidth on the L3 processor. As PBR usually can not be downloaded to CEF tables, you'd better not send all the traffic to the sup or you will cry...

> Does anyone have experience running PBR on a 6509 sup 2 or sup 720. I would like to run PBR but one of the reason not to run it is because it will spike the CPU. Is there any validaly behind that claim? Is there any cisco doc's that would list the case examples. I tried google but did not find anything usefull. Our current CPU is 3% with a 1Gig uplink. I don't see how it will increase the CPU that much. I think it is just B/S because people are afraid of change.
