AP9340 Network Card Manual: BOOTP and DHCP Configuration

BOOTP. For the Main Module to use a BOOTP server to configure its TCP/IP settings, it must find a properly configured RFC951-compliant BOOTP server.

1 . In the BOOTPTAB file of the BOOTP server, enter the Main Module’s MAC address, IP address, subnet mask, and default gateway, and, optionally, a bootup file name. For the MAC address, look on the bottom of the Main Module or on the Quality Assurance slip included in the package.

2 . When the Main Module starts, the BOOTP server provides it with the TCP/IP settings.

–If you specified a bootup file name, the Main Module attempts to transfer that file from the BOOTP server using TFTP or FTP. The Main Module assumes all settings specified in the bootup file.

–If you did not specify a bootup file name, you can configure the Main Module remotely by using the Web interface or control console; the user name and password are both apc, by default.

To create the bootup file, see your BOOTP server documentation.

DHCP. You can use an RFC2131/RFC2132- compliant DHCP server to configure the TCP/IP settings for the Main Module.

This section briefly summarizes the Main Module’s communication with a DHCP server. For more detail about how a DHCP server is used to configure the network settings for the Main Module, see “DHCP Configuration” in the Environmental Manager: Main Module User’s Guide.

1 . The Main Module sends out a DHCP request

that uses the following to identify itself: –Vendor Class Identifier (APC by default)

–Client Identifier (by default, the Main Module’s MAC address value)

–User Class Identifier (by default, the identification of the Main Module’s application firmware)

2 . A properly configured DHCP server responds with a DHCP offer that includes all of the settings that the Main Module needs for network communication. The DHCP offer also includes the Vendor Specific Information option (DHCP option 43). By default, the Main Module ignores DHCP offers that do not encapsulate the APC cookie in DHCP option

43 using the following hexidecimal format:

Option 43 = 01 04 31 41 50 43
