 Chapter 4 The Web Configurator

MGS3700-12C User’s Guide

Click the Save link in the upper right hand corner of the web configurator to save 
your configuration to nonvolatile memory. Nonvolatile memory refers to the 
Switch’s storage that remains even if the Switch’s power is turned off. 

Note: Use the Save link when you are done with a configuration session.

You could block yourself (and all others) from using in-band-management 
(managing through the data ports) if you do one of the following:

Delete the management VLAN (default is VLAN 1).

Delete all port-based VLANs with the CPU port as a member. The “CPU port” is the 
management port of the Switch.

Filter all traffic to the CPU port.

Disable all ports.

Misconfigure the text configuration file.

Forget the password and/or IP address.

Prevent all services from accessing the Switch. 

Change a service port number but forget it.

Note: Be careful not to lock yourself and others out of the Switch. If you do lock 

yourself out, try using out-of-band management (via the management port) to 
configure the Switch.

If you lock yourself (and others) from the Switch or forget the administrator 
password, you will need to reload the factory-default configuration file or reset the 
Switch back to the factory defaults.

Uploading the factory-default configuration file replaces the current configuration 
file with the factory-default configuration file. This means that you will lose all
