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 use the setting that

reflects the server that provided the TCP/IP settings (DHCP Only or

BOOTP Only):

• For a data value of 1, the After IP Assignment option is disabled, and

the Boot mode option remains in its DHCP & BOOTP setting after

successful network assignment. Whenever the MasterSwitch Plus

restarts, it will request its network assignment first from a BOOTP

server, and then, if necessary, from a DHCP server.

• For a data value of 2, the After IP Assignment option is enabled and

the Boot mode option switches to DHCP Only when the MasterSwitch

Plus accepts the DHCP response. Whenever the unit restarts, it will

request its network assignment (TCP/IP settings) 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.

For more information about the After IP Assignment, see

MasterSwitch Plus settings.
