"The processor runs two processes, Cat4k Mgmt HiPri and Cat4k Mgmt
LoPri. These two processes share total CPU usage among other IOS
processes. The reason there are two processes is when a job on the Cat4k
platform takes longer than expected or exceeds the maximum allocated CPU
time, the job is run under Low-Priority for a period of time until its
usage is reduced, giving other (Cisco IOS) processes a chance to run."
