switching, that should tell you which interfaced is getting the highest traffic
hits. then show ip interface and check for the switching method employed on the
interface. That would be a good beginning, In general, there's a chance that the
router is process-switching most of the traffic hence all you'll probably need
to do is probably re-enable interrupt switching on the interface/s
concerned.</FONT></SPAN></DIV>

<DIV><FONT face=Arial size=2>Dear Sir,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I am using Cisco 3620, IOS 12.2-17 as NAT, and
found that the CPU utilisation for IP INPUT is very high. I need to clear IP
NAT TRANSLATION every day. Could you please suggest how can I check for the
cause of high CPU utilisation.</FONT></DIV>
