Can anybody explain what "Calhoun LED Proc" process is and what it does on a Catalyst 2950 switch? Why does it utilizes that much % of CPU ? (Calhoun LED Proc - 16% while all the rest procs take ~0.00%)

Hi

AFAIK its otherwise called as Port Status Process and Led Control Process also normally it uses high percentage of cpu utilisation..

The above link does talks about the different process spec which may help you out...
