DHCP & BOOTP boot process

When Boot mode is set to its default, DHCP & BOOTP setting, the

following occurs when the Management Card is turned on or reset:

1. The Management Card makes up to five requests for its network

assignment from any BOOTP server. If a valid BOOTP response is

received to one of those requests, the Management Card starts the

network services and sets Boot mode to BOOTP Only.

2. If the Management Card fails to receive a valid BOOTP response after

five BOOTP requests, the Management Card makes up to five

requests for its network assignment from any DHCP server. If a valid

DHCP response is received to one of those requests, the Management

Card starts the network services and sets Boot mode to DHCP Only.

3. If the Management Card fails to receive a valid DHCP response after

five DHCP requests, it repeats sending BOOTP and DHCP requests

until it receives a valid network assignment: first it sends a BOOTP

request every 32 seconds for 12 minutes, then it sends one DHCP

request with a time-out of 64 seconds), and so forth.

You can configure the Management Card to always use the

DHCP & BOOTP setting for Boot mode enabling the

Remain in DHCP & BOOTP mode after accepting TCP/IP

settings option, which is disabled by default, as described in

Management Card settings.
