Network Management Card: Quick Configuration
DHCP. You can use a
\This section briefly summarizes the Network Management Card communication with a DHCP server. For more information about how a DHCP server is used to configure the network settings for a Network Management Card, see “DHCP
Configuration” in the User’s Guide.
1.A Network 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 Network Management Card’s MAC address value)
–A User Class Identifier (by default, the identification of the Network Management Card’s application firmware)
2.A properly configured DHCP server responds with a DHCP offer that includes all of the settings that the Network Management Card needs for network communication. The DHCP offer also includes the Vendor Specific Information option (DHCP option 43). By default, the Network Management Card will ignore DHCP offers that do not encapsulate the APC cookie in the Vendor Specific Information option 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
See your DHCP server documentation to add code to the Vendor Specific Information option. To disable the APC cookie requirement, see “Local access to the control console” on page 51.
To change the control console’s DHCP Cookie Is setting, use the Advanced option in the TCP/IP menu. See “Remote access to the control console” on page 52.
