Read my answer above:

I have fought this matter with the TAC for quite a long time, they were adamant:

no fix is possible (hard to believe, I know) and one has to keep it as it is.

Hi,

I have few 2960XR-48FPD-I switch which is also facing high HULC LED process.

This thread is about older models. Since your is much newer, you should try opening a case anyway to see what is Cisco response.

The most stable IOS for the 3560/3750 series of switches has always been 12.2(55)SE-train.  Try 12.2(55)SE10.  Any other IOS version is just plain garbage.

Hi Leo,

Hi Leo,

I got high cpu utilization for a long time on the same switch which is running C2960 Software (C2960-LANBASEK9-M), Version 15.0(2)SE6

I need to run the same 15.x IOs.

can you please suggest the IOS which is not affected by bug CSCsi78581.
