Quick Configuration
DHCP. You can use an RFC2131/RFC2132-compliant DHCP
server to configure the TCP/IP settings for the Management
Card.
1. A Management Card sends out a DHCP request that uses
the following to identify itself:
– A Vendor Class Identifier (APC by default)
– A Client Identifier (by default, the Management
Card’s MAC address value)
– A User Class Identifier (by default, the identification
of the Management Card’s application firmware)
2. A properly configured DHCP server responds with a
DHCP offer that includes all the settings that the
Management Card needs for network communication.
The DHCP offer also includes the Vendor Specific
Information option (DHCP option 43). By default, the
Management Card ignores DHCP offers that do not
encapsulate the APC cookie in DHCP option 43 using
the following hexadecimal format:
Option 43 = 01 04 31 41 50 43
where
– the first byte (01) is the code
– the second byte (04) is the length
– the remaining bytes (31 41 50 43) are the APC
cookie.

This section summarizes the Management Card’s
communication with a DHCP server. For more
detail about how a DHCP server can configure the
network settings for a Management Card, see
“DHCP Configuration” in the Network
Management Card User’s Guide on the Utility CD.

See your DHCP server documentation to add code
to the Vendor Specific Information option.
Note
To disable the requirement that a DHCP offer
include the APC cookie, use the DHCP Cookie Is
setting in the control console:
Network>TCP/IP>Boot Mode>DHCP
only>Advanced>DHCP Cookie Is).
