NVRAM
NVRAM (non-volatile RAM) is the place where the permanent settings are stored. This includes
- DD-WRT settings that you normally change using Web Interface
- settings for user Startup Scripts
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.
