Hi All,
I have a swich WS-C3750X-48T and i am facing the issue of high cpu utilization .
Please suggest the reason why the switch is behaving like this and what is the solution of that.
please find the log....

That's not exceptionally high , typically thw hulc led process tends to be a code issue so you might want to look at a different version or use the bug tool to see if your version has that issue.

Thanks for the reply ...
Actually I replace the old switch with this one .
The olod switch was having only 20 % of cpu utilization .
but from when I replaced the old switch with the same model 3750 the cpu utilization become 45% with the same configuration of network.
some other logs is ...
