4.4 Saving Your Configuration
When you are done modifying the settings in a screen, click Apply to save your changes back
to the run-time memory. Settings in the run-time memory are lost when the switch’s power is
turned off.
Click the Save link in the upper right hand corner of the web configurator to save your
configuration to nonvolatile memory. Nonvolatile memory refers to the switch’s storage that
remains even if the switch’s power is turned off.
Note: Use the Save link when you are done with a configuration session.
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.
