Following, in hexadecimal format, is an example of a Vendor Specific Information

option that contains the APC cookie:

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

• Boot Mode Transition. Tag 2, Len 1, Data 1/2

Boot Mode Transition enables or disables the Main Module option Remain in DHCP

& BOOTP mode after accepting TCP/IP settings, which is disabled by default.

– A data value of 1 enables the option Remain in DHCP & BOOTP mode after

accepting TCP/IP settings. When the Main Module 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 disables the option Remain in DHCP & BOOTP mode after

accepting TCP/IP settings. The TCP/IP Configuration setting switches to DHCP

when the Main Module accepts this DHCP response. Thereafter, whenever the

Main Module reboots, it will request its network assignment from a DHCP server

only.

Following, in hexadecimal format, is an example of the Vendor Specific Information

option that contains the APC cookie and the data value to disable the Remain in

DHCP & BOOTP mode after accepting TCP/IP settings:

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

TCP/IP options. The Main Module uses the following options within a valid DHCP

response to define its TCP/IP settings. All of these options except the first are

described in RFC2132.

• IP Address (from the yiaddr field of the DHCP response, described in RFC2131):

The IP address that the DHCP server is leasing to the Main Module.

• Subnet Mask (option 1): The Subnet Mask value that the Main Module needs to

operate on the network.

• Router, i.e., Default Gateway (option 3): The default gateway address that the Main

Module needs to operate on the network.

• IP Address Lease Time (option 51): The time duration for the lease of the IP

Address to the Main Module.
