Trivial File Transfer Protocol
Trivial File Transfer Protocol (TFTP) is a simple protocol that provides basic file transfer function with no user authentication.
TFTP is intended for applications that do not need the sophisticated interactions that File Transfer Protocol (FTP) provides. TFTP, together with Bootstrap Protocol (BOOTP), provides support for clients of a System i™ product.
They also provide support for other clients that use the TFTP and BOOTP protocols.
You can work with TFTP server properties through iSeries™ Navigator,
the graphical user interface (GUI) for the i5/OS® operating system.

- Configuring TFTP for clients
To allow clients to use the Trivial File Transfer Protocol (TFTP) server, ensure that the QTFTP profile has authority to access the directories and files that the clients access through the TFTP server. You also need to set the TFTP server attributes to allow the required client requests.
- Changing TFTP attributes
To change the Trivial File Transfer Protocol (TFTP) server attributes, use the Change TCP/IP TFTP Attributes (CHGTFTPA) command.
- Server ports and client ports
The Trivial File Transfer Protocol (TFTP) server uses a subnet-directed broadcast address as the destination address.
- TFTP Transfer Size option
By using the Transfer Size option, the client can determine how much data is transferred on a read request (RRQ).
- TFTP Subnet Broadcast option
Broadcast storms are a performance problem that might occur when large numbers of systems start from the network. Trivial File Transfer Protocol (TFTP) Subnet Broadcast option helps solve this problem.
- Exit points for controlling TFTP server
An exit point is a specific point in the Trivial File Transfer Protocol (TFTP) program where control can pass to an exit program. An exit program is a program to which the exit point passes control. With the use of exit programs, the experienced programmer can create customized processing when an application is running.
