Chapter 4 The Web Configurator 54
4.5 Switch Lockout
You could block yourself (and all others) from accessing the switch through the web
configurator if you do one of the following:
1 Deleting the management VLAN (default is VLAN 1).
2 Deleting all port-based VLANs with the CPU port as a member. The “CPU port” is the
management port of the switch.
3 Filtering all traffic to the CPU port.
4 Disabling all ports.
5 Misconfiguring the text configuration file.
6 Forgetting the password and/or IP address.
7 Preventing all services from accessing the switch.
8 Changing a service port number but forgetting it.
Note: Be careful not to lock yourself and others out of the switch.
4.6 Resetting the Switch
If you lock yourself (and others) out of the switch, you can try accessing via the console port.
If you still cannot correct the situation or forgot the password, you will need to reload the
factory-default configuration file.
4.6.1 Reload the Factory-default 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 9600bps with 8 data bit, no
parity, one stop bit and flow control set to none. The password will also be reset to “1234” and
the IP address to 192.168.1.1.
To upload the factory-default configuration file, do the following:
1 Connect to the console port using a computer with terminal emulation software. See
Section 3.1.1 on page 43 for details.
2 Disconnect and reconnect the switch’s power to begin a session. When you reconnect the
switch’s power, you will see the initial screen.
3 When you see the message “
Press any key to enter Debug Mode within 3
seconds ...
” press any key to enter debug mode.
4 Type
atlc after the “Enter Debug Mode” message.
5 Wait for the “
Starting XMODEM upload” message before activating XMODEM
upload on your terminal.
