Network Management Card
62
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 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 disables the option Remain in DHCP & BOOTP mode after
accepting TCP/IP settings option. The TCP/IP Configuration setting option
switches to DHCP 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 setting for Boot Mode
Transition:
Option 43 = 0x01 0x04 0x31 0x41 0x50 0x43 0x02 0x01 0x01
TCP/IP options. The Management Card 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 Management Card.
• Subnet Mask (option 1): The Subnet Mask value that the Management Card needs
to operate on the network.
• Router, i.e., Default Gateway (option 3): The default gateway address that the
Management Card needs to operate on the network.
• IP Address Lease Time (option 51): The time duration for the lease of the IP
Address to the Management Card.
