[Ewrt-devel] nvram variables

Wed Aug 4 13:22:38 PDT 2004

Changing the NVRAM variable does not force a change in the various 
settings.  And all a commit does is make the change to the NVRAM 
permanent so as to last through a reboot.  When the box reboots, upon 
startup it reads the NVRAM variables and

For example changing the gw via NVRAM won't change the routing table on 
the box.  To do that you'll need to use the "route [{add|del|flush}]" 
command.

When you make the changes via the web interface, the backend is "smart 
enough" to not only commit the changes to NVRAM, but also run the route 
command, or whatever command it needs to to enact the change immediately.
