Cisco C4507R High CPU Utilization

Ibrahim Alsharif · ‎06-13-2013

Hello Dears,

we have 2 Cisco C4507 Switches working As Core Layer, but the CPU Utilization is about 54% most of the time and sometimes it goes up to 70% or 80% also.

could you please help me to sort out what is the problem and which services are causing this utilization.

attached are the following commands:

show proc cpu sort

show proc cpu history

show platform health

show platform cpu packet statistics

show version

Thanks in Advance.

ASAK Ibrahim,

Nice way to start troubleshooting high cpu on 4500:

I will go through your data in free time and get back to you.

Not quite sure which Q is hitting more as we need to run this command couple of time.

Action plan:

==========

-> Kindly check if there are any host flapping occuring in the logs.

-> Configure Mac Move notification and you would see the flaps in the logs.

Hi Inyath,

see below logs, there are mac move notifications always.

the 2 mentioned VLANs 80 & 90 are Wireless VLANs, so I guess the movement is normal for those 2 VLANs.
