I'm facing high cpu usage on HPE5800 48Port, during the day it is above 95% and comes down to somewhat 70% during night. This wasn't the case till a month ago, the average used to be less than 20% and no changes to the network been made and no loops.

Any idea what might be the cause ?. And what are the functions of VIDL and SOCK?.

Hi,

Could you plwase share the output of below:

display version

display logbuffer reverse

Thanks!

I have disabled info-center, sflow and snmp, assuming these can cause high cpu utilisation. But it is not.

Hi,

Thank You for providing the informtion !

As I have seen, the device is running on very old firmware (2012) and it is always advisable to upgrade it to latest version because some issues related to High CPU is covered in latest version.

If problem remains after the upgrade then kindly log a case with support.

Thanks!

Deleted some lines to fix "Message cannot exceed 25,000 characters." issue here.

VIDL = the higher this is, the more idle the device is...higher is better

bRX1 - broadcast receiving high.....possible loop or other traffic causing large amounts of broadcast traffic.
