DHCP response options

Each valid DHCP response contains options that provide the TCP/IP settings that the cooling unit needs to operate on a network, and other information that affects the cooling unit’s operation.

Vendor specific information (option 43). The cooling unit uses this option in a DHCP response to determine whether the DHCP response is valid. This option contains up to two APC-specific options in a TAG/LEN/DATA format: the APC Cookie and the Boot Mode Transition.

• APC cookie. Tag 1, Len 4, Data “1APC”

Option 43 communicates to the cooling unit that a DHCP server is configured to service the cooling unit. By default, this DHCP response option must contain the APC Cookie for the cooling unit to accept the lease.

To disable the requirement of an APC cookie, see “DHCP” on page 38.

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

This option 43 setting enables or disables Remain in DHCP & BOOTP mode after accepting TCP/IP settings, which, by default, is disabled.

A data value of 1 enables Remain in DHCP & BOOTP mode after accepting TCP/IP settings. Whenever the cooling unit 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 Remain in DHCP & BOOTP mode after accepting TCP/IP settings. The TCP/IP Configuration setting switches to DHCP when the cooling unit accepts the DHCP response. Whenever the cooling unit 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
