I have the below router in production which is showing CPU usage 100% during some file transfer between the segments.
IOS (tm) C2600 Software (C2600-I-M), Version 12.3(19), RELEASE SOFTWARE (fc2)
I am using only two fast ethernet interfaces on this router which are connected to a cisco switch and are autonegotiated to 100MBPS. IP CEF is also set on the router.
Is it natural for the router to show CPU usage 100% during big file transfer? Is there any work around?
