4.4 Switch Lockout
You are locked out from managing the switch if another administrator is currently logged in. You must wait until
he/she has logged out before you can log in.
Moreover, you could lock yourself (and all others) out from the switch by:
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. Assigning minimum bandwidth to the CPU port. If you limit bandwidth to the CPU port, you may find that
the switch performs sluggishly or not at all.
Be careful not to lock yourself and others out of the switch.

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
