Inspecting CPU Utilization
The sum of the used and free memory equals the total memory. Most of the show memory summary
command output has been removed for brevity.
Do not enter the show memory summary command with the terminal length 0 command enabled. If
Note
you do, many screens of output might interrupt your session.

Select your Cisco IOS release and search under new feature documentation.
Inspecting CPU Utilization
Enter the show process cpu command and then the show process cpu history command to investigate
high CPU utilization. High utilization causes network performance problems. For example, knowing
when the router is running at over 50 percent utilization is critical. The router might start dropping
packets if an unexpected traffic burst comes through or if Open Shortest Path First (OSPF) is
recalculated. Fast switching can also be used to reduce CPU utilization.
