NVRAM

NVRAM (non-volatile RAM) is the place where the permanent settings are stored. This includes

You can run the following commands using Command Line:

nvram show

Shows the whole NVRAM content

nvram get <variable_name>

Shows variable value

nvram set <variable_name>="<value>"

Changes variable value in RAM only. Now you can play with the new settings or test user scripts but this new value will be lost after reboot unless you do nvram commit.

nvram commit

Saves all changed variables to NVRAM

Reboot the router for new settings in NVRAM to go into effect.
