MediaPack SIP User’s Manual 7. Using BootP / DHCP
Version 4.6 167 June 2005
7.3.2 Vendor Specific Information Field
The MediaPack 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 5-37 on page 128) or use the ‘-be’ command
line switch (refer to Table B-1 on page 266).
Table 7-1 details the vendor specific information field according to device types:
