Catalyst 3850 Series Switch High CPU Usage Troubleshoot

[jackson.ku]

Hi,

We have one Catalyat 3850 switch with High CPU utilization. I analysis "show proc cpu" result, the root cause of high CPU utilization is "FED" process.

I found the following documention mention how to troubleshoot the issue :

http://www.cisco.com/c/en/us/support/docs/switches/catalyst-3850-series-switches/117594-technote-hicpu3850-00.html

There are many show command, debug command and set commnad to enable detail tracking during troubleshooting step, does it cause any performance impact for the switch

Best Regards,

Jackson Ku

Wow.  That's pretty high.  But as long as there's no Output Drops you should be fine, for now.

Where can i find Most affected or repeated bugs for cisco IOS?

some bugs need special permission to access.

Is there any way to find out those ?

Talk to your Cisco SE/AM.  They have full access.
