Boot Mode Transition. Tag 2, Len 1, Data 1/2
This option 43 setting enables or disables the After IP Assignment option
which, by default, causes the Boot mode option to base its setting on the
server that provided the network assignment values (DHCP Only or
BOOTP Only):
• A data value of 1 disables the After IP Assignment option. The Boot
mode option remains as DHCP & BOOTP after network values are
assigned successfully. Whenever the Management Card reboots, it will
request its network assignment first from a BOOTP server, and then, if
necessary, from a DHCP server.
• A data value of 2 enables the After IP Assignment option. The Boot
mode option switches to DHCP Only when the Management Card
accepts the DHCP response. Whenever the Management Card
reboots, it will request its network assignment from a DHCP server,
only.
Following, in hexadecimal format, is an example of a Vendor Specific
