We have 7206 with NPG2 and 450 MB WAN link connected on gigport... Problem is we are continiously getting 90% of cpu utilization..
Can you please confirm if it can support 490 MBps of WAN link or we should upgrade the device if yes then what device is recommended.
Router is having VPN tunnle and BGP running on it.
From CPU it seems most of process utilization is due to interrupt... ============================================================ Router#sh processes cpu | e 0.00 CPU utilization for five seconds: 93%/90%; one minute: 92%; five minutes: 92% PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process 2 1238764 9425770 131 0.16% 0.12% 0.14% 0 Load Meter 5 94288636 5938203 15878 0.24% 0.12% 0.07% 0 Check heaps 76 7706641467137172 0 0.08% 0.03% 0.02% 0 ACCT Periodic Pr 81 331332736 789090215 419 2.37% 1.95% 1.00% 0 IP Input 87 1396 321 4348 0.08% 0.11% 0.03% 2 SSH Process
In this particular case if actually 490 Mbps traffic is being pushed by this box then I am inclined towards thinking that you are just pushing the box close to its limits. Is this something you have noticed recently or has CPU utilization been increasing gradually as forwarded traffic increased?
