This value reports the maximum CPU load observed during the sampled interval of the fabric-interconnect switch's onboard OS, as recorded in one archived historical sample of the fabric-interconnect switch's CPU-load and memory-usage statistics. An administrator watching for a switch supervisor becoming CPU-bound during a busy period checks this loadMax figure to catch sustained high load before it starts delaying management operations. For example, a loadMax value that stays persistently near its maximum across successive samples would prompt an operator to investigate what process on the switch's supervisor is consuming CPU.
