DHCP. You can use an RFC2131/RFC2132-compliant DHCP server to configure the
TCP/IP settings for the Rack PDU.
1. The Rack PDU sends out a DHCP request that uses the following to identify
itself:
• A Vendor Class Identifier
• A Client Identifier (by default, the MAC address of the Rack PDU)
• A User Class Identifier (by default, the identification of the application firmware
installed on the Rack PDU)
2. A properly configured DHCP server responds with a DHCP offer that includes
all the settings that the Rack PDU needs for network communication. The
DHCP offer also includes the Vendor Specific Information option (DHCP option
43). The Rack PDU can be configured to ignore DHCP offers that do not
encapsulate the vendor cookie in DHCP option 43 using the following
hexadecimal format. (The Rack PDU does not require this cookie by default.)
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 vendor cookie.
This section summarizes the Rack PDU’s communication with a
DHCP server. For more detail about how a DHCP server can configure
the network settings for a Rack PDU, see
DHCP response options .
See your DHCP server documentation to add code to the Vendor
Specific Information option.
