2960-X High CPU Usage

[Bar1s]

Hi Guys,

Recently we purchased C2960X-24TD-L. We were just trying to configure switch. 

I just noticed there is high cpu rate even the nothing is connected. 

Is it rates is normal ? It looks like high for me.

Software version is latest  : Cisco IOS Software, C2960X Software (C2960X-UNIVERSALK9-M), Version 15.2(2)E, RELEASE SOFTWARE (fc3)

Yes its normal.

It would get settledown once your configuration is complete.

Hi,

 This utilization is expected for this platform, as we can see on the show process cpu command the interrupt level is at 0% which is indicating a good behavior and the overall is 22% which normal and there is nothing to worry about.

 The only process a bit high is Hulc LED Process. The "Hulc LED" process does following tasks:

- Check Link status on every port

- If the switch supports POE, it checks to see if there is a Power Device(PD) detected

- Check the status of the transceiver

- Update Fan status

- Set Main LED and ports LEDs

- Update both Power Supplies and RPS

- Check on system temperature status

 Hope this helps, and you should not be concern at all.

Regards,

Leo
