Catalyst 2960 High CPU Utilization

Hi,

 

I have a WS-C2960S-48FPS-L running IOS Version 12.2(53r)SE and while monitoring CPU utilization I see I have a 70% average on the last 72 hrs.

Could you please advise what this "Hulc LED Process" is? Has anyone encountered this issue before?

This is not your IOS version.  This is your bootstrap version. 

 

What IOS are you running?  If you've got 2960S, then you've got two stable IOS versions to choose from:  12.2(55)SE9 or 15.0(2)SE4. 

 

Any other version is rubbish.

I have no idea what you've got in your network.  I've tested 12.2(55)SE9 and 15.0(2)SE4 on 2960S and either versions are stable.
