I cannot understand this show process cpu output that I'm seeing on a couple of catalyst 6500.
In particular I cannot understand the 96% of CPU usage for Kernel/Idle process while the global CPU is 5-6%
Does anybody have idea of this ?
CEDACRINORD_6500_C> (enable) sh proc cp
CPU utilization for five seconds: 3.30%
one minute: 4.00%
five minutes: 4.00%
PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process
--- ----------- ---------- -------- ------- ------- ------- --- ---------------
1 0 0 0 96.70% 96.00% 96.00% -2 Kernel and Idle
2 2 68 1000 0.00% 0.00% 0.00% -2 Flash MIB Updat

That is the idle CPU and expected to be close to 100%

It is self explanatory.
Your case 4% is the actual processor utilization.
Which will increase if any new process is running.
So processor is idle for 96% and which will reduce if any new process gets started.
processor % utilization = 100% - idle % utilization

Could I ask you the reason of this ?

Ahh ok so I understand now what it means. It's the CPU free....
Thanks to both of you: I thought it was a kind of background usage,
