BootP
The Bootstrap Protocol (referred to as
BootP) function allows the 8270 to
participate in RFC 951-compliant environments. BootP uses User Datagram
Protocol (UDP) to formulate a network request to allow a device to configure its IP
address for a given logical 8270.
Step 1. Edit the BOOTPTAB file on the BootP server (see “Editing the
BOOTPTAB File” on page 4-7).
Step 2. Initiate the BootP daemon ( BOOTPD) on the BootP server.
Step 3. Make sure that the IP State in the IP Configuration Menu is set to BootP
When Needed or BootP Always.
Step 4. Initiate the BootP transfer by resetting the 8270. A BootP is automatically
initiated after diagnostics have been completed.
Note: Do not configure multiple BootP servers to a single 8270.
The BootP sequence consists of IP address determination and bootfile selection, if
configured, using BootP request and reply.
In order for you to utilize the BootP function, a BootP server must be configured on
the network. This BootP server must reside on the same subnet as the 8270. A
typical implementation might consist of a BootP daemon (BOOTPD or
IN.BOOTPD)
or something similar. BOOTPD reads a startup file called
BOOTPTAB. This file
