We noticed a *minor* increase in CPU. Ie, a 7206 moving around about 10 to 12 mb/s on average, with 8 ethers, 8 T1', 2 HSSIs, and one fast ether, on a NPE-150 with 128 Megs, about 12 peers (5 of which are fairly active), two full views, running 11.1.17CA, was doing around 30% on average. With NetFlow on every interface, it moved up to about 36%. FYI, CEF was about 24%. 'sho proc c' shows most of the CPU going to IP Input: CPU utilization for five seconds: 34%/32%; one minute: 36%; five minutes: 36% PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process 17 150791508 36649565 4114 0.32% 0.46% 0.48% 0 IP Input On Fri, 15 May 1998, Dave Curado wrote: > > Does anyone have any data points they'd share regarding > the impact of netflow export on cpu load?
