Chapter 5 The Web Configurator

5.5 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 MES-2110.

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 MES-2110.

8Change a service port number but forget it.

Note: Be careful not to lock yourself and others out of the MES-2110. If you do lock yourself out, try using out-of-band management (via the console port) to configure the MES-2110.

5.6Resetting the MES-2110

If you lock yourself (and others) from the MES-2110 or forget the administrator password, you will need to reload the factory-default configuration file or reset the MES-2110 back to the factory defaults.

5.6.1 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 previous configurations and the speed of the console port will be reset to the default of 9600 bps with 8 data bits, no parity, one stop bit and flow control set to none. The password will also be cleared and the IP address be set to 192.168.0.254.

To upload the configuration file, do the following:

1Connect to the console port using a computer with terminal emulation software.
