Hi folks. On a cisco AS5800, what are the parameters that could be tweaked to reduce CPU utilization ? With 360 active calls here's what i have: NAS01-MTNDODS#sh proc cpu | exclude 0.00 CPU utilization for five seconds: 79%/17%; one minute: 81%; five minutes: 80% PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process 3 80428996 4609093 17450 2.19% 1.08% 0.78% 0 Check heaps 7 147676920 1554810 94984 2.43% 4.42% 3.93% 0 Serial Backgroun 29 8102432 16740884 483 0.08% 0.18% 0.18% 0 Net Background 61 11903404 9770801 1218 0.24% 0.22% 0.23% 0 ISDN 74 8349756642098634624 397 7.72% 6.99% 6.93% 0 IP Input 76 3189204 1447125 2203 0.08% 0.04% 0.04% 0 CDP Protocol 79 665792 8520105 78 0.16% 0.13% 0.10% 0 IP Background 91 795916 2427196 327 0.08% 0.19% 0.23% 0 PPP IP Route 92 31107300 5726565 5432 38.09% 45.42% 45.05% 0 PPP IPCP 120 80886604 2196656 36822 0.73% 0.74% 0.74% 0 Compute load avg 148 32705256 345451242 94 4.30% 2.52% 2.07% 0 PPP Events 156 3841144 63989161 60 0.08% 0.06% 0.03% 0 IP SNMP 158 8978492 27800036 322 0.16% 0.26% 0.16% 0 SNMP ENGINE 210 222569208 2670597 83340 5.60% 5.39% 4.83% 0 AAA Per-User As you see that IPCP process takes ~ 45% of the CPU. Is there a way to disable TCP header compression completely ? Or any other CPU intensive things ? It's an AS5800 with NPE-300 Thanx Paul ************************************************ Paul Khavkine Network Administrator DISTRIBUTEL Communications. 740 Notre Dame West, Suite 1135 Montreal, Quebec, Canada, H3C 3X6 1-514-877-5505 x 263 http://www.distributel.net ************************************************
