51.3 Switc h C o nfig ura tio n

I lost my configuration settings after I restarted the Switch.

Make sure you save your configuration into the Switch’s
nonvolatile memory each time you make changes.
Click

Sa ve

at the top right corner of the web configurator to save the configuration permanently. See

also

Section 39.2.2 on page 341

for more information about how to save your configuration.

I accidentally unplugged the Switch. I’m not sure which configuration file will be loaded.

If you plug the power cable back to the Switch, it’ll reboot and load the configuration file that was used
the last time. For example, if

C o nfig 1

was used on the Switch before you accidentally unplugged the

Switch,

C o nfig 1

will be loaded when rebooting.
