Syntax

logging history {flash ram} level no logging history {flash ram}

flash - Event history stored in flash memory (i.e., permanent memory).

ram - Event history stored in temporary RAM (i.e., memory flushed on power reset).

level - One of the level arguments listed below. Messages sent include the selected level down to level 0. (Range: 0-7)
