• From version 4.4 to version 4.4 or to any higher version, the device retains its configuration
(ini file), however, the auxiliary files (CPT, logo, etc.) may be erased.
When using the Software Upgrade wizard, available through the Web Interface (refer to Section
5.11.1 on page 78), the auxiliary files are saved as well.
Note: To save the cmp file to non-volatile memory, use the -fb command line switches. If the file
is not saved, the gateway reverts to the old version of software after the next reset. For
information on using command line switches, refer to Section
B.11.6 on page 198.
10.3.2 Vendor Specific Information Field
The Mediant 2000 uses the vendor specific information field in the BootP request to provide
device-related initial startup information. The BootP/TFTP configuration utility displays this
information in the ‘Client Info’ column (refer to Figure B-1).
Note: This option is not available on DHCP servers.
The Vendor Specific Information field is disabled by default. To enable / disable this feature: set
the ini file parameter ‘ExtBootPReqEnable’ (Table
6-1 on page 90) or use the ‘-be’ command line
switch (refer to Table B-1 on page 198).
Table
