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:

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.

If you lock yourself (and others) from the Switch or forget the administrator password, you 
will need to 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 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.
