BOOTP Server
The BOOTstrap Protocol (BOOTP) software, compliant with RFC 951, is used to
assign IP addresses to nodes on an Ethernet network. Devices (hosts) on the
network issue BOOTP requests during their initialization sequence, and a BOOTP
Server that receives the request will extract the required IP address information from
its database and place it in BOOTP response messages to the requesting devices.
The devices will use the assigned IP addresses, received from the BOOTP Server,
for all communication occurring on the network.
Your NOE
BOOTP Server
Your NOE x0 module comes supplied with a BOOTP Server. This feature allows you
to provide IP addresses to all the I/O devices being serviced by the NOE771x0.
Providing a BOOTP Server that is built into your NOE771x0 module eliminates the
need for you to have a dedicated PC on your I/O network acting as a BOOTP Server.
You can configure your NOE771x0’s BOOTP Server from the module’s HTTP Web
page. Using this feature allows you to add, remove, and edit devices to the BOOTP
Server’s database, which is maintained on the modules non-volatile memory.
Note: The BOOTP Server is available on the 140NOE771 -00 and -10 models.
Note: The NOE771x0’s BOOTP Server cannot be used to provide its own IP
address.
