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