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).
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
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.
