Chapter 4 The Web Configurator

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.

4.5 Switch Lockout

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

1Delete the management VLAN (default is VLAN 1).

2Delete all port-based VLANs with the CPU port as a member. The “CPU port” is the management port of the Switch.

3Filter all traffic to the CPU port.

4Disable all ports.

5Misconfigure the text configuration file.

6Forget the password and/or IP address.

7Prevent all services from accessing the Switch.

8Change 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.

4.6Resetting 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.

4.6.1 Reload the Configuration File

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