2.2.1.2. Using Data
New configuration data, stored in "working configuration", cannot be used for
the MultiPort/LT's real-time gateway operation until transferred to "master
configuration".
The command CONFIGURE USE copies the contents of the "working
configuration" to the "master configuration". Refer to Figure 2-10.
Once configuration is complete, the CONFIGURE USE command
must
be used
before the new data affects gateway operation.
The relationship between "master" and "working configurations" minimizes
the possibility of configuration errors affecting the MultiPort/LT's real-time
gateway operation.
All data can be displayed and checked for accuracy before transferred to the
"master configuration".

2.2.1.3. Saving Data
The Config Flash EPROM is used to permanently save configuration data.
The contents of the "master configuration" are lost during a MultiPort/LT
power off/on or reset cycle. However, during such cycles, the contents of the
"hardware Flash EPROM" are retained and copied to the "master
configuration".
