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:
1 Delete the management VLAN (default is VLAN 1).
2 Delete all port-based VLANs with the CPU port as a member. The “CPU port” is the
management port of the Switch.
3 Filter all traffic to the CPU port.
4 Disable all ports.
5 Misconfigure the text configuration file.
6 Forget the password and/or IP address.
7 Prevent all services from accessing the Switch.
8 Change a service port number but forget it.
"
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.
4.6 Resetting 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.
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 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 configuration file, do the following:
1 Connect to the console port using a computer with terminal emulation software. See
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.
