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 managing the Switch if you do one of the following:
1 Delete or modify 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.
