LAN Interface Configuration
Bootp & Store
When “Bootp & Store” is selected, the parameters obtained from a Bootp
Server become the active parameters immediately. In addition, they are stored
to the non-volatile memory of the card. Thus, after a power cycle they are still
available. This enables a kind of “bootp once” configuration of the card.
Example: The user may not want to have a Bootp Server be active in his
network all the time. But on the other side, he may not have any other
configuration method than Bootp. In this case he starts the Bootp Server
temporarily, powers on the card using the initialization mode “Bootp &Store”,
waits for the Bootp cycle to be completed, closes the Bootp Server and powers
off the card. Then he selects the initialization mode “Using Stored” and powers
on the card again. From now on, he is able to establish the TCP/IP connection
to the card with the parameters obtained in that single Bootp cycle.

NOTE
Use the initialization mode “Bootp & Store” carefully, because writing to the non-volatile
memory takes time. Therefore, when the card shall obtain its parameters from a Bootp
Server every time it is powered on, the recommended initialization mode is “Bootp”!
