When applying changes over ssh you’ll need to “write” or “save” the changes. Usually you’ll edit the \/tmp\/system.cfg config file and then save the changes with one of the following commands.<\/p>\n\n\n\n

\/usr\/etc\/rc.d\/rc.softrestart save\nor\ncfgmtd -f \/tmp\/system.cfg -w && reboot<\/pre>\n\n\n\n
rc.softrestart has some advantages.  It does not require the radio to reboot when making changes to things like SNMP or the device name.<\/p>\n\n\n\n
It does seem to have issues sometimes with certain changes.  The following happened when attempting to replace the whole \/tmp\/system.cfg with a previous backup config.<\/p>\n\n\n\n

If you have issues applying changes with the softrestart, you can try it with cfgmtd.  Downside is the radio does reboot.  <\/p>\n\n\n\n
cfgmtd -f \/tmp\/system.cfg -w && reboot <\/pre>\n\n\n\n
You could potentially take the reboot off the end of the above command, but have had random issues in the past where the only way to fix it was a physical reboot.  Having the radio reboot after applying the config seems to resolve the issue<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"
