Network Management Card

DHCP response options

Each valid DHCP response contains options that provide the TCP/IP settings that the

Management Card needs to operate on a network, and other information that affects

the Management Card’s operation.

Vendor Specific Information (option 43). The Management Card 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 Management Card that a DHCP server is configured

to service APC devices. By default, this DHCP response option must contain the

APC cookie for the Management Card to accept the lease.

DHCP

BOOTP

The default setting. The Network Management Card tries to obtain its TCP/IP settings

from a BOOTP server first, and then, if it cannot discover a BOOTP server, from a

DHCP server. If it obtains its TCP/IP settings from either server, it switches this setting

to BOOTP or DHCP, depending on the type of server that supplied the TCP/IP

settings to the Network Management Card.

Click Next>> to configure the same settings that are on the BOOTP Configuration

and DHCP Configuration pages

and to specify that the DHCP and BOOTP setting

be retained after either type of server provides the TCP/IP values.

Setting Description

1. The default values for these three settings on the configuration pages generally do not need to be

changed:

• Vendor Class: APC

• Client ID: The MAC address of the Network Management Card, which uniquely identifies it on the

local area network (LAN)

• User Class: The name of the application firmware module

To disable the requirement of an APC cookie, see DHCP.
