46.3 Switch Configuration

I lost my configuration settings after I restart the Switch.Make sure you save your configuration into the Switch’s

nonvolatile memory each time you make changes. Click Save at the top right corner of the web configurator to save the

configuration permanently. See also Section 38.3 on page 286 for more information about how to save your configuration.
