Hi Diana,

I am using cat4500-entservicesk9-mz.150-2.SG8.bin in my Cisco 5410R SW. Please suggest do i still need to upgrade IOS.

Thanks in advance.

Do you see something in your logs when this problem is present? can you provide your "show log" output? and Can you provide the output of this comand "show platform health"?

Hello!

The output of the K2CpuMan Review process is high, I need you can provide me the output of the "show platform cpu packet statistics", but send me this when you have gotten enough statistics, for about an hour or more. I will try to help you, you also can read this document from Cisco. http://www.cisco.com/c/en/us/support/docs/switches/catalyst-4000-series-switches/65591-cat4500-high-cpu.html

---Do not forget to rate useful answers---

Regards,

Hi Diana,

Please check the attached Text for show platform cpu packet statistics. Please help .

Hi Daina,

Please find output...please help to reduce high CPU utilization
