High CPU utilization issue

[rahil khan]

Dear ALL,

I recently configured PAT on core switch 6500. But after putting some PCs in inside VLAN facing problem of cpu utilization crossing above 50%. Here is the sh proc cpu output

I have attached nat translation log file. Kindly suggest how to mitigate this issue.

Hi,

As per the NAT translations the IP 10.1.1.50 is doing more and it seems doing more tranlsation with port 21 (FTP) which is causing to high cpu.
Please trace the above IP and if possible remove it from network or check why the user using doing more translations.
Once you controle that IP your cpu will get down.

If this answered you please click on correct answer.
