The settings of some configuration parameters are derived from those of other parameters. When a parameter is changed, any parameters derived from that parameter are automatically updated.

Any derived parameter can be set in "protected" mode, which means that the Configuration-By-Forms utility or Configuration Manager cannot recalculate the derived value. Protected mode allows you to set a desired value for the parameter, even though the value is normally derived by the system from other parameters.

If protected mode is disabled, the value of the parameter is adjusted whenever new values are set for other parameters on which the derived value is based. The new and old values are shown in the change log.

For detailed steps on performing these procedures, see the online help.
