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

Information option that contains the APC cookie and the disable Boot Mode

Transition setting:

Option 43 = 0x01 0x04 0x31 0x41 0x50 0x43 0x02 0x01 0x01

See DHCP & BOOTP boot process.
