4500-X - CPU process K5CpuMan Review

[a.auvinet]

Hi Everybody,

I have 2 4500-x in VSS mode.

The CPU core 1 is 92  79 and 67 %

 But when i do sh processes cpu sorted

Do you kow what is  the process K5ForerunnerPacketMa ?

Why when I do "sh processes cpu sorted", the sum of process see less than 92% ??

Cdlt,

IOSd means the switch has link(s) that are being overutilized.  Check each interface and determine which one has the highest amount of "output drops".

[a.auvinet]

Ok.

I done "clear counter" on all interfaces.

I will see in one hour  if 4500-x has one or more interfaces with "output drops".

[a.auvinet]

There aren't of "output drop" on interfaces.

What firmware is the chassis running on? 

After the output above, is the CPU still high?

[a.auvinet]

Hi,

Firmware is  Version 03.08.01.E RELEASE SOFTWARE (fc2)

I juste did clear counter, yes the CPU still high.

Core 0: CPU utilization for five seconds: 27%; one minute: 24%; five minutes: 24%

[a.auvinet]

I did "sh platform health"

[Leo Laohoo]

When you remote into the switch, is the response time sluggish or is it snappy?

[a.auvinet]

The reponse time is very good.

No problem.

not sluggish  or snappy.

[a.auvinet]

Perhaps I worry for nothing

[Leo Laohoo]

I agree.  Could be "cosmetic".  

Just keep monitoring.
