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 Switched Rack PDU
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 management
card accepts the DHCP response. Whenever the PDU 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
