APC Network Management Card AP9617 - Manual (Page 13)

Quick Configuration
DHCP. You can use a RFC2131/RFC2132-compliant DHCP
server to configure the TCP/IP settings the Management Card
needs.
1. A Management Card sends out a DHCP request that use
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 of 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 will ignore DHCP offers that do encapsulate the APC
cookie in the Vendor Specific Information option using
the following hexidecimal 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 briefly summarizes the Management
Card communication with a DHCP server. For
more detail about how a DHCP server is used to
configure the network settings for a Management
Card, see “
DHCP Configuration” in the Network
Management Card User’s Guide
(.\doc\usrguide.pdf).
Refer to your DHCP server documentation
for information about adding code to the
Vendor Specific Information option. To
disable the APC cookie requirement, see
“Local access to the control console” on
page 14 or “Remote access to the control
console” on page 15 to change the control
console’s DHCP Cookie Is setting, an
Advanced option in the TCP/IP menu.
