EEPROM parameters. The parameters allow administrators to control variables such as the default boot

macros, and device aliases. NVRAM is where the system identification information is stored, such as the

host ID, Ethernet address, and time-of-day (TOD) clock.

Examples of NVRAM variables:

diag-device net The diagnostic startup source device. diag-file Empty string Arguments passed to the

startup program in diagnostic mode. diag-switch? false Whether to run in diagnostic mode
