How BootP Service Works

When an instrument is powered on, an LAN Interface in the instrument
broadcasts a request for an IP address or host name and provides its hardware
MAC address as an identifier. The Agilent BootP Service answers this request
and passes a previously defined IP address and host name associated with the
hardware MAC address to the requesting instrument.
The instrument receives its IP address and host name and maintains the IP
address as long as it is powered on. Powering down the instrument causes it to
lose its IP address, so the Agilent BootP Service must be running every time
the instrument powers up. If the Agilent BootP Service runs in the
background, the instrument will receive its IP address on power-up.
The Agilent LAN Interface can be set to store the IP address and will not lose
the IP address if power cycled.
